AVAILABILITY AND PRICES

WHICH COMPUTER?

DYNACOMP distributes programs for all of the computers and systems listed on the facing page.
However, not all programs run on all computers. To avoid confusion, we have chosen a consistent way
of indicating which runs on what. This information accompanies the description of each program, and
is also shown in the availability tables.

Beneath the title of each program description is a simple caption having one of four forms:

1. “X, Y and Z only"

2. “available for all computers"

3. “available for all computers except X, Y and Z"

4. “CP/M only"

The meaning of the first form is self-evident. The second one means all of the computers listed
under "COMPUTERS AND REQUIREMENTS" and "SPECIAL FORMATS". The third form means all
of those computer except "X, Y, and Z". The fourth notation ("CP/M only") is a shorthand for the
following:

CP/M=Osborne, North Star CP/M, SuperBrain, NEC PC 8000 CP/M, KAYPRO II
MORROW DESIGNS, HEATH ZENITH Z-100, HEATH ZENITH H-89 8"

CP/M, CROMEMCO, ALTOS, XEROX 820,1BM PC/PC Jr., SANYO (with MS DOS),
PANASONIC, COMPAQ Z or BA, CANON AS-100, DEC RAINBOW 100 (with MS
DOS), and other CP/M IBM 3740 systems.

Unless otherwise noted, "CP/M only" also means that Microsoft BASIC is required.

WHICH CP/M?

DYNACOMP's CP/M-Microsoft BASIC programs are compatible with CP/M 1.4, 2.2, and MP/M, and with
Microsoft BASIC versions 4.51, 5.2 (or higher), and the BASIC-80 interpreter. No special printer or screen
graphics capabilities are required unless specifically noted.

SINGLE OENSITY/DOUBLE DENSITY

DYNACOMP recommends that if your computer accepts both single and double density diskettes, you
should order the software you want in the single-density format and later convert it to double density. If you
want double density, add $3.00 to the diskette price shown in the program description.

The exceptions to this recommendation are the North Star Advantage, Kaypro, and Osborne-1 double
density model. The North Star Advantage will simply not read single-density disks. The Osborne-1 and
Kaypro double-density systems do, but with perhaps 90% reliability. We strongly recommend that double¬
density disks be ordered for these machines.

HOW MUCH MEMORY IS REQUIRED?

A point of possible confusion is how much memory is required to run a particular program. Unless otherwise
stated, all of DYNACOMP's programs will run in'16K of program memory for all machines except the Atari
which requires 24K. (Several of DYNACOMP's Atari programs will run in 16K and are so marked.) This means
that for an Apple 11 Plus disk system, 32 K is required (so that at least 16K of memory is available after the disk
operating system is loaded). For a CP/M system, the 16K refers to how much memory is free for use after
BASIC has been loaded. Programs which require more memory are so indicated.

AND THEN THERE IS THE COMMODORE

PET/CBM programs are available on both cassette and diskette. However, the diskette versions can be
loaded only using 2040, 4040, and Commodore 64 or 128 disk drives. For those having 8050 drives (or
wishing to save money), the cassette versions may be loaded and saved on diskette. However, the cassette
versions save data to tape only!

PACKAGE PRICES

There are several groups of software packages which naturally form sets. Examples include the three Fourier
analysis programs, the three regression programs, Volumes I and II of BASIC SCIENTIFIC SUBROUTINES,
the NSSE library, and others. DYNACOMP offers each of these groups at a reduced package price. These
reduced-price packages DO NOT count toward the 10% and 20% quantity discounts indicated on the order
form.

AUTHOR MESSAGE

A CALL FOR AUTHORS

SOFTWARE ACQUISITION

Over the past two years DYNACOMP has been adding
from ten to fifteen new titles to its product line each
month. Also, during the same period, DYNACOMP has
averaged about twice as many conversions. This pace
has increased more recently and our plans are to triple
the new-addition rate.

DYNACOMP gets its software from a variety of sources:

1. In-house development

2. Acquisition of titles from other companies which:

a) Have ceased active operations

b) Wish to have another marketing channel

3. Outside authors

This message is directed to the potential DYNACOMP
author.

CRITERIA

If you are the author of a good piece of software in any
of the subject areas covered in the DYNACOMP
catalog, you should consider DYNACOMP as a possible
publisher for your work. Our criteria for acceptance are:

1. Marketability. Is this a product which provides a
useful function (solves problems, is entertaining,
etc.)?

2. “User-friendliness". Is the program carefully
thought out, error-trapped, and easy-to-operate?

3. Documentation. Does the instruction manual
provide step-by-step instructions, include back¬
ground information, examples, sample sessions,
etc.?

REVIEW PRIORITIES

Quite frankly, the first thing the DYNACOMP reviewer
will look at is the associated manual. From that will be
formed an impression of how well documented the
software is. Next the reviewer will operate the program
and form an impression with respect to the “user
friendly" characteristics.

REVIEW PROCEDURE

The usual review procedure is simple. The author
submits the software package for review and DYNA¬
COMP reviews it, usually within two weeks. There are
three possible review outcomes:

1. Acceptance. You will receive signed royalty
agreements and a letter indicating any required
changes or additional materials.

2. A statement of interest and suggested modifi¬
cations to make the package acceptable.

3. A response indicating no interest.

ROYALTIES

Our compensation policy is simple. We pay a 1(K20%
royalty on the gross sales, and pay this monthly (not
quarterly or semi-annually as do other companies).

MARKETING APPROACH

In the past DYNACOMP has depended on magazines
for its main advertising thrust. However, the prolifer¬
ation of magazines has made this approach much less
effective than earlier in the business. This change,
coupled with a mailing list which exceeds the circula¬
tion lists of most magazines (the first printing of our
144-page Catalog No. 28 was over 250,000 copies!) has
resulted in a new marketing emphasis — direct mail. It is
estimated that over 500,000 people will have read
Catalog No. 28. Therefore our marketing is two-fold:
magazine ads to generate interest in the catalog and
large mailings of catalogs.

DISTRIBUTION

DYNACOMP's distribution is world-wide:

• DYNACOMP has over 3,500 dealers in its active
mailing* list, and over 500 dealer accounts around the
world.

• DYNACOMP software is being translated and
marketed in French-speaking countries.

• DYNACOMP software is sold through other catalogs
(for example, COMPUTRONICS, K-12 Micro Media,
A.W. Peller, ASM, and many others).

HOW MANY CAN WE SELL?

The question every author has on his or her mind is
"How many of my packages do you expect to sell?" Our
answer is simple and honest: we don't know! The
software market is unpredictable and strewn with
inflated figures and broken promises. Some programs
which we think are great do not ever take hold. Some
require a year of exposure. Some become hot sellers
almost instantly. After more than seven years in the
business, what we have learned is not to be cocky and
to just do a good job in presenting software products
with clear and detailed descriptions.

According to a recent survey, DYNACOMP is in the top
10% with respect to software publishing company sales,
so we must be doing something right. We will try to do
right by you, too. It is in both of our interests to sell your
product.

For further information, contact Mrs. B. Rivers,
Marketing.

SPECIAL NOTE FOR ENGINEERS AND SCIENTISTS

The president of DYNACOMP, whose background is in
nuclear and solid-state physics, along with some
electrical and design engineering, is particularly fond of
technical programs and reviews them himself. What he
is looking for are "user friendly" and well documented
programs which deal with engineering applications,
physical simulations, advanced tutorials, mathematical
utilities, etc. Needless to say, these submissions get
speacial treatment!

PUBLIC DOMAIN SOFTWARE
CAUTION!

Sour Grapes!

The public domain software appearing in this catalog
was written by a variety of people, some professionals,
most not. This software is not copyrighted and is
generally not of commercial quality. In most cases there
is NO documentation or, if there are instructions, they
are on the disk itself and are either skimpy or poorly
written. There are exceptions, however.

The point of this warning is to emphasize that these are
not DYNACOMP programs, and we do not support
them. Further, they are sold AS IS. We will replace
magnetically defective disks, but cannot afford to give
phone help or refunds for unsuitable programs.

DYNACOMP is supplying this material as a public
service and we do not want you to become angry with
us if you find these programs difficult to use or simply
faulty.

The Plus Side

This material is a great value for the price. For those who
wish to experiment or just get a feel for what is available
in the public domain, this is an excellent opportunity.
The risk is low, and the chances of finding a useable (for
you) piece of software is good. If nothing else, twenty
dollars' worth of public domain software can keep you
busy for quite some time!

IMPORTANT NOTE
FOR ATARI 800 XL OWNERS

The Atari 800 XL is not completely compatible with the
Atari 800. This means that some of DYNACOMP's
software may not run on the 800 XL without the Atari
translator disk. This disk is available from Atari (good
luck) or DYNACOMP ($5.00). If you have an 800 XL you
will eventually need this disk!

gfc APPLE MACINTOSH 2j|
W ANNOUNCEMENT W

Slowly, but surely, DYNACOMP is bringing on line
Macintosh versions of many of the programs shown in
this catalog. We waited to do this because, quite frankly,
a 128K Macintosh is simply not capable of running our
software! Now that the 512 K Mac is available, the
situation has changed.

To run the available DYNACOMP programs you will
need a 512K Mac and Microsoft BASIC, release 2.0 or
newer.

The packages available are marked with a MAC! in the
margin of the description box. Try BRIDGE MASTER.
You'll love the graphics!

Note: There is an additional charge of $5.00 for all Mac
packages to cover the extra media and production
costs.

TRS-80 MODEL III, 4, 4P FORMATS

(Read this if you have a Model III, 4, or 4P)

Here is the problem: Unlike IBM, Radio Shack has not
maintained direct upwards compatability between all of
its various computer models. For example, none of
DYNACOMP's TRS-80 software will run on the Model II
or Model 16.

As for the Models III, 4, and 4P, there is some measure
of compatibility, but it is not complete. The difficulty to
you, as a customer, is that DYNACOMP cannot maintain
a complete inventory for each TRS-80 model. Therefore,
when we state "TRS-80'' (without a Model III or 4
qualifier) we mean that the diskette sent to you will be
in Model I format unless you special order (see below)
another format. If you have a Model 111 or 4 (or 4 P), here
is what you need to do to use the standard DYNA¬
COMP diskette:

Model III: You must format a blank system diskette and
use the TRSDOS 1.3 CONVERT command to copy the
DYNACOMP files from the Model I format diskette to
your Model III format diskette. That is easy! TRSDOS
1.3 comes (came) with all Model Ills.

Models 4 and 4P: You must run your machine in the
Model III mode. We have been told by many Radio
Shack representatives that there is a keyboard com¬
mand which accomplishes this. However, no one seems
to know what it is. As far as we can tell, you must boot
your system with a TRSDOS 1.3 system diskette to do
this, and use CONVERT (see paragraph above).
TRSDOS 1.3 does not come with the Model 4, but can
be easily obtained through your Radio Shack dealer. It is
recommended that you obtain a TRSDOS 1.3 system
diskette in any case to expand the selection of software
available to you.

SPECIAL ORDER FORMATS

If you do not want to do the CONVERT yourself, or do
not want to obtain a TRSDOS 1.3 system disk to run
your Model 4 in the Model III mode, DYNACOMP can
specially prepare Model III diskettes for you with a
service charge of $5.00 per diskette. These diskettes
will work on both Model III and Model 4 machines.

FOR THE BEST PRICES ON EXCELLENT QUALITY
DISKETTES, SEE OUR SUPPLIES SECTION. WE DO
NOT SELL THE REJECTS, SECONDS, OR REDUCED
SPECIFICATION DISKETTES WHICH ARE NOW
BEING SOLD AT “AMAZINGLY" LOW PRICES. THEY
ARE NOT SO AMAZING IN QUALITY!

APPLE CP/M AVAILABILITY

In response to the many requests for Apple CP/M
format programs, DYNACOMP has converted most of
its CP/M software to that format. The packages which
are not available are those requiring hardware-specific
cursor control codes.

The not available list includes: BRIDGE MASTER,
MONEY, BOOK KEEP, TYPE-RITER, TEACHER'S AIDE,
PORTFOLIO MANAGEMENT, MINI-LEDGER, CUSTO¬
MER PROFILE, DATEBOOK, TAX OPTIMIZER, PER¬
SONAL BALANCE SHEET, all SuperSoft programs, DATA
PLOTTER, BLACKJACK COACH, TRIVIA MANIA, and
CASINO CRAPS. Many of these are available in
"regular" Apple DOS format.

In general, you will need a full 64K of RAM and
Microsoft BASIC release 4.51 or newer (unless other¬
wise specified) to run DYNACOMP's Apple CP/M
software.

Be careful to specify "Apple CP/M" when ordering.

NOTE: Apple CP/M is treated as a special format. There
is a $5.00 extra charge for supplying diskettes in this
format.

WHAT IS THE

8-INCH IBM 3740 FORMAT?

Before the appearance of the 5V«" diskette came the 8"
disk. It was originally used on IBM equipment, and IBM
carefully specified the acceptable format under the
code "IBM 3740". By today's standards, this is a single¬
sided, single-density soft-sectored format with 128
bytes per sector (256 bytes per sector would be double¬
density) and 77 tracks on one side of the disk.

Older 8" CP/M systems use this format exclusively.
Newer 8" CP/M systems use double or quad density,
double-sided format disks, but can usually read the
standard IBM 3740 format. If you are unsure as to
whether or not your system can read IBM 3740 format
disks you can:

1. Call your dealer.

2. Call the manufacturer of your drives or computer.

3. Gamble a few dollars and buy one IBM 3740
public domain disk and give it a try.

BEWARE THE CHEAP DISKETTE!

During the past year, the prices of diskettes have
dropped remarkably. Also, in many cases, so has the
quality. It looks like several well known manufacturers
have lowered their costs (in an attempt to be competi¬
tive) by cutting corners in manufacturing.

From what we can tell, it looks like some companies are
not polishing the media as well as they used to. Diskettes
having dull magnetic surfaces, or ones showing blem¬
ishes or diagonal (chatter) marks should be avoided: they
will haunt you!

For 5V4" diskettes, we are currently selling only one
brand: Nashua. It is not unusual for DYNACOMP to run
10,000 Nashua diskettes through its duplication facilities
and turn up only one bad diskette. Nashua diskettes are
not only good, but they have the smoothest surface (as
discussed in a BYTE Magazine product comparison), and,
as we have found, have the highest reliability of all brands
tested (and we have tested quite a few!).

Ye'-, you may be able to find cheaper diskettes, but they
are cheaper, not /ess expensive (in terms of what you get
lot vour money). DYNACOMP usually does not recom¬
mend one brand over another, hut you shoulff know that
our production group loses Nashua diskettes’

IF YOU HAVE

A JAPANESE COMPUTER ...

Be careful!

If you have a Toshiba, Sanyo, etc., your version of
Microsoft BASIC (e.g., TBASIC, SBASIC) may not be
useable with DYNACOMP software! If your release
number (displayed upon sign-on) is less than 4.0 (e.g.,
Release 2.2), then you share something in common with
the old Altair BASIC (1976); age or incompatability with
the modern versions of Microsoft BASIC (release 4.51,
5.2, BASIC-80, etc.).

Another way to tell whether or not your BASIC is
compatible with post-1980 Microsoft BASIC is to check
on how disk files are "opened". Do you use OPEN F$
FOR INPUT AS #1 or OPEN "I", 1, F$? The first
format dates back to Altair BASIC (1976); the second is
more recent.

OUR APOLOGIES!

We are now running at capacity (1,500 Ibs/day) in our
catalog department. The DYNACOMP mailing list now
exceeds 800,000 people, and we simply can't send each
edition of the DYNACOMP catalog to every individual.

To be as fair as possible, we have established a priority
system in which DYNACOMP customers will be placed at
the front of the list for receiving catalogs. Once catalogs
have been sent to our customers, we will ship to others on
the list randomly until the next edition is available. Then
we will start with the customer list again.

What this means is:

• Customers will receive new catalogs as they
become available (two to three times each year).

• Non-customers will, on the average, receive one
catalog each 18 months.

IF YOU HAVE AN IBM “COMPATIBLE”

or...

IF YOU ARE ORDERING SPECIAL
FORMAT CP/M DISKETTES

DYNACOMP's IBM and Microsoft BASIC programs are
usually saved on the disk as tokenized code. That is,
they are saved in a "language" that can be read by IBM
BASIC (in the case of MSDOS) or MBASIC (release 4.51
or 5.1, in the case of CP/M). This may be likened to a,
form of "shorthand" writing. It takes less disk space than
saving the programs in "longhand", and the programs
load much, much faster.

The problem is that not all BASICs use the same
shorthand. Even some of the very old versions of
Microsoft BASIC (like those being sold with many
Japanese computers—they must have gotten a good
price on the ten-year-old software) use a different
shorthand. The same is true with many of the BASICs
supplied with IBM compatibles; they are not truly
compatible with IBM BASIC tokenized code.

However, 99% of the time this problem can be
circumvented if you order special "ASCII" versions of
the products you want. When you order "ASCII", we
convert the "shorthand" to "longhand' so that your
BASIC will be able to load the programs without errors
in interpreting the tokenized code. The service charge
for this is S5.00 per disk.

CONSULTING

DYNACOMP ENGINEERING CONSULTING

DYNACOMP is pleased to announce the establishment of a separate
consulting group within the main organization of DYNACOMP, Inc.

In the past, DYNACOMP's staff has consulted for companies such as
Xerox, McGraw-Hill, Racal-Vadic, etc., in the areas of image science,
simulation, statistics, data analysis, ^nd software engineering. Several of
DYNACOMP's software products are either direct or indirect outgrowths of
this work. For example, TRANSFER FUNCTION ANALYZER was originally
written to analyze speaker response; FOURIER FORECASTER addresses
issues raised in a commodities market assignment; REGRESSION II was
designed to analyze xerographic line copy profiles; HARMONIC ANA¬
LYZER was written to study image noise; etc.

As DYNACOMP's engineering software capabilities have grown, it has
become increasingly apparent that DYNACOMP has both the tools and
resources to take on larger and broader commitments in the consulting
profession. In particular, DYNACOMP's internal staff, combined with its
contributing software authors, brings a blend of talents which can be very
effective in assignments involving computer analysis.

This group is managed directly by DYNACOMP's president and founder,
Dr. F. R. Ruckdeschel.

Dr. Ruckdeschel was formerly an R&D Manager and Principal Scientistat
the Xerox Corporation. He has authored over 35 technical papers, as well as
two texts on scientific programming. In addition, he has been awarded 14
patents.

Dr. Ruckdeschel directs each consulting assignment. He personally
scopes the task, chooses the appropriate staff member(s), establishes and
monitors the schedule, and reviews all reports. In this way you can be sure of
high quality, efficient work which clearly addresses your needs.

Often we are able to modify existing DYNACOMP software to suit your
particular situation, thereby saving in consulting time by not having to start
from scratch.

The areas in which DYNACOMP has particular expertise are:

• Image science/color theory • Statistics

• Electrical engineering • Mechanical engineering

• Scientific programming • Mathematics

• Fourier analysis • Simulation

• Data analysis/curve fitting • Physics

• Programming in most languages

If you have need for consulting in these areas, contact Ann Taylor at

CONVERSION SERVICE

As you might imagine, DYNACOMP maintains quite a
bit of software and hardware in support of its widely
varied line of products. We therefore have the
capability of converting files on disks and diskettes of
one format to disks or diskettes of another.

The 5V4-inch diskettes which we can transfer files
between are shown under the heading "DYNACOMP
SPECIAL ORDER FORMATS" (see page 3). For example,
we can move CP/M files from XEROX 820-11 diskettes to
Televideo 803 diskettes.

and dated copy of the following:

"I,_, hereby give DYNACOMP per¬

mission to perform the indicated disk/diskette conver¬
sion. I also state that I have the right to have such format
conversions made, and that no copyrights are being
violated. In the case of any litigation involving this
conversion, I hold DYNACOMP blameless in their
service, and accept all legal and financial responsibility."

Signed:_

Date:_

An 8W x 11" copy of this statement is also available
from DYNACOMP by written request.

We can also transfer (either way) between IBM MS-
DOS and IBM CP/M-86 format diskettes; between 5V4-
inch CP/M (and MS-DOS) and 8-inch CP/M disks (IBM
3740 SSSD); and between CP/M (and MS-DOS)
diskettes and Apple Z-80 CP/M or Apple DOS 3.3

please send only copies, not the originals, and pack
them well so they will not be bent or otherwise
damaged.

These prices include the blank disks or diskettes
needed to produce the new formats.

More complicated conversions can be constructed from
the above table. For example, conversion from 8-inch
CP/M IBM 3740 format disks to Apple Z80 CP/M could
be accomplished by 8-inch CP/M to 5Y4-inch MS-DOS
SSDD conversion ($30.00), and from there to Apple
Z80 CP/M ($35^0), for a total of $65.00 per 8-inch
CP/M disk, plus $3.50 for shipping and handling.

to very carefully specify the format of the disk or
diskette you want converted, and the format you want it
to be converted to. Your source disk(s)/diskette(s) will

THE COMMODORE 128

The COMMODORE 128 is a very interesting machine.
First, it can be run in the C-64 mode. This means that all
of DYNACOMP's C-64 software can be run on the 128!

Second, in the CP/M mode, you can "read" all of DYNA¬
COMP's Kaypro and Osborne (double density) disk¬
ettes. Except for programs which specifically use the
hardware features of the Osborne or Kaypro, you can
run all of DYNACOMP's CP/M software (and we have
the largest CP/M selection available).

Sorry, we do not support the third mode in the C-128;
we do not think that it will have lasting popularity.

HODGE PODGE

(Apple, Atari, C-64, IBM, and TRS-80 only)

HODGE PODGE is a computer “happening" for children
from ages 18 months to seven years and older. It is a
surreptitious learning device which provides knowledge
in a most enjoyable (and non-intimidating) fashion. The
program consists of many cartoons, animations, and
songs which appear when any key on the computer is
pressed. Each key provides something different for the
child to explore, from Apples to Zigzags. With an adult
present the child can be told about magnets, numbers,
musical notes, animals, up and down, color, and much,
much more. When alone the child will be kept endlessly
amused by the color, sound, and wonderful pictures
displayd by HODGE PODGE. This program is a must for
any family containing children and a suitable computer.
Note: the TRS-80 version does not have the sound
feature of the Atari and Apple versions. Apple and TRS-80
versions require 48K; Atari cassette version requires 32 K,
diskette version requires 48K.

DYNACOMP's HODGE PODGE was such a great success
that we decided to produce another package aimed at the
pre-school child, CHILDREN'S CARROUSEL

CHILDREN'S CARROUSEL is composed of nine menu-
selected games which have great color and sound (inclu¬
ding the carrousel and alphabet songs). The games include
matching shapes, counting, letter recognition and more. It
has been "field tested" with many children. We are very
proud of this one!

CHILDREN’S CARROUSEL

April 14, 1984 edition. Computer Screening column.)

CHILDREN'S CARROUSEL, $19.95, Dynacomp, Inc.,
1427 Monroe Avenue, Rochester, N.Y. 14618, for Apple
and Apple compatible:

Nonreading children from 2 to 6 will love to run this
musically motivated program. There are nine games
designed for children to use on their own, but you will
probably want to go through the games once with each
child to be sure he understands what to do.

The object of the program is to teach various skills in a
colorful and interesting manner. There are no scores kept
and if any answer is wrong, only a buzz is given.

When the child answers correctly, a portion of the
Carrousel Horse appears. When the correct number of
horses (different for each game) are completed, the
Carrousel turns and plays.

The skills taught are: alphabet recognition, co-ordination
in the use of computer keys, shape recognition, shape
comparison, shape differentiation, color differentiation,
letter matching, and numbers.

Each game is unique. For the alphabet-recognition game
the “Alphabet Song" is played, and with each note the
appropriate letter appears. Then, in letter recognition
and matching, the alphabet is presented in random order.
Four letters appear on the screen, and the child is to press
a key which matches any of these letters. The keys are
supposed to be laser guns, and when the correct key is
pressed the letter explodes, disappears, and is replaced
by another.

Preschool children will find this an enjoyable way to
learn, and parents will have bought a program that their
children will be able to use without too much super-

by mixing education and fun.

TINY TUTOR, a simple math program aimed at children
from 3 through 7, presents easy additiortand subtraction
problems in clear, graphic style. Numbers are presented
both numerically and graphically by small trolley cars that
move with a delightful "chug-a-chug"; three trolley cars
plus four trolley cars equals seven cars on the track! All
problems are shown in this friendly fashion which im¬
mediately puts children at ease; the child simply counts
the trolley cars to arrive at the correct answer. The
problems range in complexity from 1—0 to 10+9 and
TINY TUTOR keeps tabs on the child's progress in order
to limit the complexity according to ability. Tl NY TUTOR
is also a patient program; there is no time limit in which a
problem must be answered. A question mark simply
flashes prompting your child's entry of the answer.
Correct answers are rewarded with cheerful sound
effects and the arrival of a new problem "train". If three
incorrect answers are given to a problem, the answer is
simply provided and the next problem appears. At the
end of ten problems, the child's score is graphically and
numerically represented; 10 out of 10 receives an addi¬
tional sound-effect bonus.

TIME MASTERS'

(Atari only)

TIME MASTERS" is an entertaining way of learning time
concepts for children ages 3 to 10. It is especially helpful
for children having difficulty mastering clock time. Be¬
sides teaching children how to read clocks, this program
also teaches days of the week, months of the year, and
holidays. Each month of the calendar has a picture
illustrating the season as an associative aid for the child.
Holidays are highlighted on the calendar; selecting the
day displays a picture of the holiday on the screen.
Moving the hands of the clock makes the date in the
calendar change as midnight is passed.

There are three playing modes in this educational game: a
self-learning mode which children can use to learn by
experimenting with the clock and calendar; a clock-test
mode; and a day-of-the-week tester. Each test has its own
series of changing rewards for right answers. After a short
test, the child gets to take a break by playing a colorful
music game. A greater number of correct answers earns a
greater amount of play time. The program is self-paced
and designed to minimize the need for reading skills and
outside assistance.

Requires a joystick (or a trackball) and a disk drive.

PLANET MATHEMATICA

(Commodore 64 only)

PLANET MATHEMATICA is a powerful combination of a
fast-action video game and a math education program.
This combinatidh, while blending the excitement of
computer gaming with the effectiveness of computer-
based education, leaves the accent squarely on the
entertainment side in order to hold the interest of the
student. The sole object of the game is to achieve the
highest score possible by destroying alien invaders. The
math portion itself becomes a competition against time
to get back into the game with as much time left as
possible. Each math problem is carefully presented in
order to show the student that larger multiplication or
division problems are actually solved by breaking them
into smaller, more manageable problems. Unlike most
other math educational programs that simply ask for the
answer to a complex problem, leaving the method of
solution up to the student, PLANET MATHEMATICA
actually presents all of the intermediate steps of long
division, multiplication, addition, and subtraction. These
features make PLANET MATHEMATICA a truly educa¬
tional program that students will find difficult to resist.

AMERICAN FLAGS

(Atari only)

AMERICAN FLAGS is a colorful and educational game
that teaches you to identify the state, provincial, national,
and territorial flags of North America. Can you recognize
your local flag?

These flags make a fascinating display of design and color.
Some of the flags of Canada have their origin inEngland,
Scotland, Ireland, and France and some feature fleurs-de-
lis or the Union Jack. Most of the flags of the United States
have their origins in military banners and are often used
with a yellow or fringed edge or a lance-head. Do you
know which state flags feature Indian emblems, the Big
Dipper constellation, a bear, an eagle, a pelican, or an
anchor?

To get to know these important symbols, you can enter
the name of a state or province and display its flag on the
screen with some information about the area. Each flag is
drawn on a high-resolution full-color screen, with some
using as many as ten different colors and shades!

Also, you get a full-screen color map of North America
indicating the area represented by the flag. This will give
you a graphic illustration of distance and the contrast in
size between areas, such as tiny Rhode Island and huge
Alaska. You'll also hear some of the more popular state
and provincial songs and the national anthems in their
entirety, all with four-voice arrangement.

You can take a quiz on all 76 flags, or only the flags of
Canada or the United States. There are over 300 clues to

SHAZAM ELECTRIC COMPANY

(IBM only)

SHAZAM ELECTRIC COMPANY teaches a basic con¬
sumer skill: how to read a utility meter. This program
simulates ten different kinds of meters and challenges
the student to read them accurately, record each
setting, and calculate the bill for each meter.

SHAZAM is designed primarily for use in secondary-
level math classes; it reinforces basic calculator and
record-keeping skills. And, before the end of each
session, feedback is given on the accuracy of all
calculations.

A Teacher's Log is maintained. It contains a color-coded
summary of each student's performance and the
readings and calculations for the meters used. These are
useful for tracking student progress and identifying skills
which may need help (e.g., subtraction, multiplication,
rounding of decimals, reading the meter, etc.). A sample
meter face, reporting form, and sample screen displays
are provided for use as advance organizers.

SHAZAM is menu driven and, therefore, very easy to
use.

SHAZAM requires an IBM-PC or compatible computer,
PC-DOS version 2.0 or MS-DOS version 2.02 or higher,
196K of RAM, BASICA version 2.0 or higher, one 360K
disk drive, and a high-resolution graphics monitor and

CAPITAL ATTACK

(Commodore 64 only)

The purpose of this game is to teach students the names
and correct spellings of the states and their capitals.

Earth is under attack by aliens from the planet Xenon.
Wave after wave of interplanetary ballistic missiles are
being launched at the United States. As commander of
defenses, your job is to defend all of the 50 states and
their capitals.

Powerful anti-ballistic missile bases are located right
outside each of the capitals. When a missile is detected
heading toward a state, you must type in the name of the
capital of the state in order to launch your ABMs and
destroy the Xenon missile.

Don't delay! There is only a limited amount of time before
the warhead hits. As you watch the clock tick down on the
missile approach, you must quickly think of the answer
that will launch the counter-attach and save the state.

NATIONAL FLAGS

(Commodore 64 and Atari only)

NATIONAL FLAGS isa colorful and entertaining way to be
introduced to the national flags of nations across the
world.

The main function of flags is social communication. They
represent or identify the existence, presence, origin,
authority, posession, loyalty, glory, beliefs, or objectives
of an entire nation. Many countries suggest through their
symbols the importance of agriculture, industrialization,
flora, fauna, dynasties, unity, liberty, justice, democracy,
progress, victory, the sun, the sky, the sea, or religion as
the hope of the future.

To get to know these important symbols, you can display
a flag plus a world map on the screen and read the
accompanying information about the nation's currency,
capital, and population. You can take a quiz, either on the
flags of the nations of the world, or one specific region:
Africa, the Americas, the Middle East, Europe, or Asia-
Pacific. You'll be surprised how colorful and unusual
some of these flags are! The world list, including 168
different nations, will challenge even the most advanced
student of geography.

NATIONAL FLAGS is impressive in terms of its graphics,
the amount of information contained in the program, and
its educational value.

Requires 48K.

NATION

(Apple only)

NATION is a contemporary strategy game that puts you
at the head of your own island nation. Your decisions
are the law-of-the-land, dictating whether your nation
grows into an industrial giant or falls into economic
chaos beneath the feet of invading armies. NATION
provides you with the once-in-a-lifetime experience of
governing millions of people.

By controlling agriculture, industry, health care, housing,
the military, and the national treasury, you try to
develop the most prosperous nation while keeping your
opponent from doing likewise.

Waging war, blockading your opponent's coastline,
building industrial empires, promoting the national
defense, and taxing your people are just some of the
many options you can choose from during each turn of
the game. Providing a food supply, houses to live in, and
hospitals to heal in are examples of the responsibilities
needed to maintain the happiness of your people.
Greedy pirates and Nature's deadliest weapon, hurri¬
canes, add to the complexity.

As well as exciting head-to-head competition, NATION
provides a challenging solitaire game. Four different
computer opponents, each employing distinctive strat¬
egies, provide hours of thought-provoking enjoyment.

Colorful HI-RES graphics with easily recognizable
symbols, fast play, a thorough, easy-to-understand
instruction booklet, and the friendliest input system
ever created for a strategy game make NATION a real
winner!

ELIZA II

(Available for all computers except
Commodore, North Star (BASIC) and Atari)

This is the well known artificial intelligence program
which was originally written by Joseph Weizenbaum
for the large computers at MIT. ELIZA simulates a
session with a psychotherapist who analyzes your
comments and responds accordingly. This program
has gained particular recognition for its surprising
ability to provide realistic responses to your state¬
ments, and has often been referred to in reference
to Turing's test for human intelligence.

DYNACOMP's version of ELIZA is unique in that
several new features have been added without
compromising the quality of the original. For example,
the range of the dialogue has been increased and
the responses are less patterned. The entire exchange
may be saved and recalled from disk. You can save
and continue sessions later. You may add in your
own code (the program is in BASIC) to extend
ELIZA'S abilities. And more! However, don't take
ELIZA'S responses too seriously. After all, it's only a
computer (or is it?)!

YOUR FIRST ATARI DISK

(Atari only)

YOUR FIRST ATARI DISK is a disk full of educational
programs. Included are:

• An autocataloging program.

• An autobooting program.

• A sound-demonstration program and tutorial.

• A new and unique hangman program with five 100-
word lists, letter shooting, and a maze.

• A graphics demonstration.

• Three programs for math, alphabet, and stick art.

The autocataloging and autobooting programs may be
copied onto your own disks. You may customize your
own disks by having the catalog autoboot, then select
your program by catalog number.

The hangman game is not the simple variety you've seen
elsewhere. This version contains five word lists (each
containing 100 words) of increasing difficulty. You may
also build your own word lists. Also, the game has been
made a bit more intricate by adding joystick control, an
energy maze, passwords, etc.

The remaining four programs are interesting on their own,
but more importantly, form frameworks for more elabor¬
ate programs which you may write!

Requires 48K and one disk drive.

APPLE INTRODUCTION

(Apple only)

APPLE INTRODUCTION provides 31 different pro¬
grams intended for use by students in grades 3 through
high school.

The programs may be classified into 3 major areas. First,
there are those which provide instruction in the use of
the Apple computer. These include instruction in
interpreting error messages, how to solve minor
problems, practice in finding keys via touch typing,
using the various keys to produce art and music, and
familiarization with certain computer vocabulary. Sec¬
ond, there are programs which use formulas (area,
compound interest, classifications of triangles according
to side measurements, making change, etc.). Finally,
there are quizzes. Included here are arithmetic (whole
numbers, fractions, decimals, percents), word problems,
English grammar, and spelling (applicable to foreign-
language study).

Once a program is selected from the menu, the diskette
may be removed. Therefore, in a classroom situation,
each student does NOT need his own diskette.

Several of the programs are done in color, and the ART
program provides for a paper copy of the picture drawn
if a printer is available.

You are first shown a list of all countries that won
medals in the 1984 SUMMER OLYMPICS, including the
number of gold, silver, bronze, and total medals
received. There is a quiz (randomly generated) about
the 20 countries that won the greatest number of
medals. The percentage of questions answered cor¬
rectly is given at the end of the set. You may also choose
a specific country to be quizzed on. In this case, the
computer chooses a second country and a set of
comparison questions is generated about the two of
them. There are numerous combinations of questions
so that repetition is kept to a minimum.

WEATHER FORECASTER is a statistically-based analysis
package that will predict average temperatures (30-year
means) for any day of the year as well as heating degree
days, cooling degree days, number of frost free days,
growing seasons, and corn heat units. It will give you a 3-
day weather forecast based on current time factors. In
the long term it will simulate a 3-day weather forecast
any day of the year for your location, including 3-day
weather maps.

You are not limited to ground level predictions. You can
get an average forecast of conditions at the inter¬
mediate upper air levels of 1,000, 850, 700, and 500
millibars. If you have current upper air readings from the
weather service you can analyze the upper air using
these parameters (and check on the weather service!).

WEATHER FORECASTER can be used for regions within
the following geographic coordinates: 0° to 90° North
latitude and 0° to 180° West longitude.

Predictions displayed include:

• Cloud cover/type/height

ADVANCED MATH GRAPHICS

(Apple and IBM only)

ADVANCED MATH GRAPHICS (AMC) is a menu-driven
collection of seven programs which graphically (HI-RES)
demonstrate many of the functions and concepts
encountered in advanced high-school and beginning
college mathematics.

The subject areas covered are:

• Polynomial functions

• Rational polynomials

• Trigonometric functions

• Polar plotting

• Conic sections (2D)

• Conic sections (3D)

• Fourier series

For each of the seven choices there is a variety of
functions which can be plotted, and you can choose the
coefficients which go with each functional form. Also, you
may vary the screen parameters: size of each axis; tic
distance; X, Y increments; multiple functions (on top of
one another); etc.

The three-dimensional conic section plots are particu¬
larly interesting to view, and the Fourier series approxi¬
mations to square waves (and other functions) are very
informative.

Every step in AMC is menu-controlled and error trapped.
Each graph can be saved on disk for later recall. Includes
an excellent 32-page instruction manual.

OHM'S LAW

(Atari only)

If you are learning electronics, then OHM'S LAW will
solve your problems dealing with resistance, current,
voltage and power. Of course, if you just sit back and let
OHM'S LAW do all the work for you, you will not learn a
thing! But it will certainly check your answers for you to
guarantee they are correct. It will also solve those prob¬
lems you claim cannot be solved "because there is not
enough information", unless, of course, you are right and
there really is not enough information. It will point out to
you that the problem can be solved and you are just not
trying hard enough.

OHM'S LAW will give you a better insight into what you
are trying to learn. It may be used to point out subtleties
overlooked in the learning process. The program's ability
to perform so many calculations in a very short period of
time will allow you to perform many experiments to see
more clearly the relationships often overlooked because
of the time it takes to make all those time-consuming
calculations.

The program can also be used to solve Thevenins's and
Norton's theorem problems as well as "T" circuit, bridged
"T" circuit and lattice network problems and can aid you
when your're designing actual electronic circuits.

OHM'S LAW will not perform magic, nor will it do
anything that you yourself cannot do. (Well, maybe it can,
but it wasn't planned that way.) But it will do the
calculations much, much faster than you can!

It is not necessary to enter any formulas when you use
OHM'S LAW. All formulas and special-case relationships
are built into the program. There are over 400 of them!

Requires 48 K to run. A printer is supported but is not
necessary.

HANGMAN

Reprinted with the permission of
SOFTALK magazine.

George Earl’s hangmen play the traditional game, except
that they tell you right out what’s to go in the blanks—in another
language. C’est une bagatelle maisje vous Voffreavec amour is
what you’re to put in--. —--- -

LATIN, FRENCH and SPANISH
HANGMAN

(Availability, see below)

The HANGMAN series offers a new and educational twist
on the classic Hangman game. It may be played one of
four ways (we will take Spanish as an example):

1. Sentences — English to Spanish

2. Sentences — Spanish to English

3. Vocabulary — English to Spanish

4. Vocabulary — Spanish to English

You are presented with the word or sentence in one
language and you have to construct the translation. There
are over 400 sentences and more than 1,500 words
(depending on disk capacity) to work with. Level: approx¬
imately first-year language course.

This is a fun way to get started with a language. The
Hangman series has received a rave review (see Review
section) in Softalk magazine.

with Calamitas virtutis occasio est. Hmmra.

Come back, all you French and Latin students of five or fifty
years ago. Well, did you solve those two? Don’t feel bad.
George Earl’s hangmen are terrific for students, but there’s a
whole league of closet users who just think they’re a ton of fun.
See, the programs work just like hangman. You guess letters.
So, when jeunefille is so familiar but just beyond that little twist
in memory, put a couple of letters in and you’ve got it! Such a
memory. If you become a closet addict too, don’t tell anyone,
just enjoy.

The fact is, you can learn or relearn a lot about languages
from these packages. There are selections to study the vocabu¬
lary and syntax before you play die game. (Closet addicts never
look at these first. They take their memory trials straight.)
They’re well done, and using the computer to leam them really
is the spoonful of sugar that makes the medicine of learning go
down.

But the games are the neat part You can choose from among
several configurations, or do them one after another; vocabu¬
lary (individual words), English to other language, other
lan guag e to English; sentences (the whole ball game!), English
to other language, other language to English. There are also
several levels of configuration.

Incredibly, the sentences and words are interesting. There’s
little of “The pen of my aunt is on the table” (in French, please?)
or “The boy is a soldier from Gaul” (Latin Scholars, groan in
unison). Instead, try these:

La solitude est a Vesprit ce que la diete est au corps.

Esfeo, por otro lado, es rico.

Non semper facilem habet felicitas aurem.

In the French and Latin games, the words to be translated
and the letters you type in are in big, bold, pleasing hi-res type,
complete with appropriate accent marks. All the games keep an
on-screen record of your percentage of accuracy for that round.
(Closet players: ignore it.)

The wonderful thing is that when you get done with the disk,
you’ve learned a whole lot of another language. Child or adult,
it’s the same. Combining these very well done programs with a
language class would seem an unbeatable move. B

INTERNATIONAL
VOCABULARY MANAGER

(Atari only)

IVM was designed for use by the individual student of
foreign language. It is well adapted to classroom use as
w/r>!! and nrovidps a number nf tools useful to the

Each student can create word lists which may be
reviewed for study, printed out, and modified. There is
no limit to the number of lists. Separate lists can be set
up to correspond to lessons, chapters, general topics,
etc. The lists are automatically alphabetized.

INTERNATIONAL VOCABULARY MANAGER generates
quizzes on the screen, or prints them out on paper.
Quizzes can be set up to test for knowledge of either
the foreign word or phrase, or its English equivalent. For
on-screen quizzes, results for each student are saved for
later review by the instructor. During the quiz, the
correct answer is displayed after each answer is given.
Incorrect items are repeated and are asked first at the
next quiz session. Printed quizzes are set up on paper
with an answer key, and are ready to be duplicated for
classroom use.

Among the valuable utilities provided is a simple word
processor, which allows creation of text in any of the
languages covered. A sample word <ist is provided for
each language to get you started. IVM is extremely "user
friendly". The languages covered are: Dutch, English,
French, German, Italian, Latin, Spanish, and Swahili. In
addition, Russian capability is provided through a
special character set Lists and quizzes will print out
adequately with many printers, but to obtain all accent
marks, and to print Russian, a Star, Gemini, or Epson
printer is recommended.

Requires 48K of RAM, and one disk drive. A line printer
is optional.

SPELL MASTER II

(CP/M and IBM only)

SPELL MASTER II is simply the most extensive spelling-
education and word-utility software package available.
First, SPELL MASTER II contains a spelling vocabulary of
over 35,000 words. This spelling list contains words
ranging in difficulty from the very simple to the very
difficult. Second, SPELL MASTER II can be operated in
several modes:

Games:

• Standard Hangman
e Unscramble

e Guess the missing letter(s)

Utilities:

• Scrabble helper

• Spelling checker
Experimental:

e Create your own use for SPELL MASTER ll's
vocabulary.

The games offer various difficulty levels based on word
length, amount of scrambling, and the number of
missing letters.

The Scrabble" helper will take the letters you specify
and display the possible words which can be made from
those letters. You can even make the search conditional
(e.g., there must be an E in the third position and an N in
the fifth position).

The spelling checker can work on most ASCII text files
created by the popular word processors. It is not an
elaborate (or fast) checker, but it does a good job at
catching those typos you never seem to be able to see.

The programs comprising SPELL MASTER II are written
in BASIC. They are supplied in two versions: expanded
and REMarked source listings, and compacted code (for
speed). This allows you to make changes if desired, and
possibly to compile them. In addition, a utility is
provided for adding words to the vocabulary to suit your
needs. This vocabulary is not protected and consists of
simple ASCII sequential files which you can easily

LANGUAGE DRILL

(IBM only)

LANGUAGE DRILL provides a very effective way to
rapidly memorize foreign language vocabulary. Using
either one of the supplied beginner's lists (French,
German, Spanish, Italian, Dutch, and Swahili), or a list
entered by the student or teacher,^the user is drilled on
words selected randomly from the list. After an incorrect
(or partially correct) answer is given, the complete
correct answer is displayed. Incorrect responses are
drilled more frequently, until they have been correctly
translated three times in succession.

Words in the drill list can be changed, deleted, or added
to. Statistics are kept regarding the number of sessions,
number of trials in each session, and the number of right
and wrong answers in each session. Words which have
been incorrectly identified are retained and drilled
again at the next session.

Several students can use the same disk for the same or
different languages. Each student's list is kept separately
so that the drilling is tailored to that student's needs.
Students may also use the same disk for more than one
language.

LANGUAGE DRILL can be used for teaching English
vocabulary to foreign students since the program will
present either the English word (or phrase) or the
foreign word (or phrase) as the item to be identified.

LANGUAGE DRILL is intended for use by students at
the high school level or above, and for adults learning a
language on their own. It is the best and most

SPELL MASTER II comes on several disks. One disk
contains the BASIC programs. The other disk (or two, or
three, depending on your machine) contains the

SPELL MASTER II is fast in the game mode, but
moderately slow (depending on the size of the search)
in the word-comparison mode. (We have done some
"smart" things to optimize the search and comparison
procedures. Some of our methods might even be called
clever!) However, when in the search mode, SPELL

THE READING PROFESSOR

(Apple, IBM, and CP/M only)

The best way to describe this package is to print
excerpts from a review (J. A. Lewis in Educational
Curriculum, August, 1984):

"The Reading Professor is a good tutorial for increasing
your normal reading rate. There is a difference between
reading for comprehension and skimming for highlights.

The bulk of the material in the Reading Professor is
aimed toward increasing your normal reading rate. The
techniques covered are basic and easily transferrable to
everyday reading. The reading passages chosen are
interesting and enjoyable. . . .

"The Reading Professor consists of two parts—the
Lessons and the Exercises. The lessons consist of ten
parts which take 15 to 20 minutes each to complete. It
is by no means necessary to do all of these at one sitting.

.. . The Reading Professor steps you thru the lessons in
sequence. If you turn the machine off and start another
day, your progress is recorded and you begin where you
stopped.

"The lessons can be repeated within the same profile,
but are not recorded over your original scores. You must
begin a new profile with a new name (or erase the old
one) if you wish to see a new lesson profile. The
interesting part of the profile for me was the graph.
While my reading speed increased steadily as 1
progressed through the lessons, my comprehension
showed an inverted bell curve. As 1 applied the
increased speed techniques, comprehension fell off and
then increased as 1 continued to increase my speed. My
overall increase was 30% in speed and 10% in
comprehension. This is quite a remarkable increase for
such a small investment of time. Even further recom¬
mendation comes from the fact that the skills have been
retained and 1 can already use them in daily reading.

"When using the exercises, you can choose from 50
different passages and seven different types of exer¬
cises. You have the option to choose eight variables for
the exercises which include character size, line width
and reading speed, among others... The narrow line
width allows me to practice on newspaper column
width. The variable which allows you to turn the
background off means that you can only see the
highlighted words or phrases. This quickly shows if
you're are reading faster or slower than the rate you
have chosen because you cannot look back or ahead.

" Conclusion: For someone who is genuinely interested
in increasing their normal reading speed as opposed to
speed reading, 1 feel the Reading Professor can be very
useful. The Appendix A has a good passage regarding
the rationale of speed reading and 1 recommend
reading it I will continue to use the exercises and feet 1
will continue to increase my reading speed and
comprehension."

The basic READING PROFESSOR comes with a general
interest reading library. Extra libraries (Junior High,
Professional, and College) are available.

RAPID READER

(Apple, Atari, and C-64 only)

This time, instead of our describing the product, we will
let a reviewer do it (from InCider, September 1983, by
Brian Murphy; reprinted with permission). We have
included the entire review:

Woody Allen once told a classic joke about speed
reading: "I took a speed reading course. I read War and
Peace in just two hours. It's about Russia."

Of course the point of the joke is that anyone can read
quickly, but reading quickly with comprehension is not
easy.

If the aesthetics of writing are a secondary consider¬
ation and if your studies or work require the absorption
of large amounts of information, then speed reading is
important. RAPID READER trains your eyes first to take
in whole words at a rapid pace, then pairs of words, then
phrases, short sentences, and finally long sentences.
The trick to fast reading is to learn to take in more than
just one word at a time as you read. RAPID READER
allows you to approach these skills gradually. You learn
to read word by word and then in clusters of words.

A good first step with the RAPID READER program is to
find out your reading speed. The Speed Test option
found on the main program menu will allow you to
select a speed from 50 to 1500 words per minute and a
difficulty level from 1 to 4. Once you've made that
selection, the program will flash a series of sentences on
the video screen. After each sentence appears on the
screen, it will reappear with a word missing, which you
must supply. The computer will monitor your answers
and evaluate your performance.

This is not a real comprehension quiz; there are limits to
what a personal computer can do. It cannot judge an
essay you write describing the content of the test
sentences, but it can determine if you have retained
what you've read. At the highest level of difficulty, you
are shown two complex sentences. You then fill in a
blank for one word (missing from one) of them.

The next step is to build up your speed. If you test out at
400 wpm at the start, key in the Words option from the
main menu and practice reading single words at 500
wpm or faster. Once you are comfortable at a new
speed, you move to the Word Pairs, Phrases, Short
Sentences, and Long Sentence routines. By the time you
are comfortable with Long Sentences you should be
reading, with comprehension, at the speed you have
selected.

To test yourself, select again the Speed Test option from
the main menu, and going from levels 1 to 4 of difficulty
at your new word speed, see if you really are reading as
fast as you'd like. If you need more work, you can always
go back to the tutorial options.

One of the many nice things about this software is the
option to change the words used to make sentences.
You can use this feature to add words from a foreign
language—turning the program into a language tutorial
as well as a reading program! A Spanish word list is
included on the disk.

This is one of the most accessible educational software
packages available. The documentation amounts to one
page, but even that much is unnecessary. The system is
so logical and the program is so self-explanatory that its
operation can be mastered in just a few minutes.

As for RAPID READER'S adaptability to the classroom,
there remains some dcubt. This is not a self-checking,
record-keeping, or grading program. Without some
outside means of evaluating progress, the program can
only be used as an aid for more motivated students. For
students and professionals who really want to improve
their reading speed, the RAPID READER is a most
valuable aid.

PRIMER 83

(Apple only)

As you will see from this description, PRIMER 83 is a
unique and effective learning package designed for
people with impaired reading skills.

A synopsis of the story behi nd PR IM E R 83 should f i rst be
told. Many of you may already know of it from newspaper
accounts.

PRIMER 83 was originally written to aid in the rehabili¬
tation of a 30 year old man suffering from “word blind¬
ness" (dyslexia). He had a brain tumor which, after
removal, resulted in selective memory loss. He worked
with many traditional exercises with limited success.
With the incentive of sponsorship from Johns Hopkins
University, PRIMER 83 was developed to address the
needs of this individual and other people with this
handicap. PRIMER 83 worked. It also appears to be
effective with individuals having other general reading
problems.

PRIMER 83 is the culmination of the combined efforts of
several people, including the original "student", an ex¬
pert programmer, a grammaticist, a musician, and several
others. It is well thought out and tested.

REQUIREMENTS

• The user does not need to have prior experience with
a computer or have typing skill.

• A moderate-quality cassette recorder is needed: The
instructions given in the manual are also recorded on
tape.

• A 48K (or more) RAM Apple II or lie with one disk
drive is needed.

• A black-and-white monitor.

• A paddle connected to port #0 (controls display
speed).

• A printer is optional. (Used for printing-out test sta
tistics and analyses).

• An ECHO II speech systhesizer is optional. (Used for
letter and word prompting — nice but not vital.)

Note that a black-and-white monitor is required. Color
displays generally do not have the resolution of the black-
and-white units. There is no point in further handicap¬
ping the student with a low-resolution display.

MODULE DESCRIPTIONS

PRIMER 83 contains several program modules. The main
ones are:

• TALKWRITER — This program is designed to familiar¬
ize the user with the keyboard. The keyboard is shown
on the screen along with the letter to be typed. If an
ECHO II is present, the letter's name will be spoken.

• LETTER FLASH — Letters are flashed on the screen
and the user has to press the corresponding key. The
duration of the flash may be preset as well as the
permitted response time. The results may be saved on
disk and analyzed later (see TROUBLE SHOOT,
below).

• WORD FLASH — This has the same features as
LETTER FLASH. The prompts come from a 600-word
vocabulary of common words. These words are organ¬
ized into 24 groups of 25 words each (e.g., ROAD
SIGNS, SIMILAR WORDS, etc.). With ECHO II, each
word can also be spoken. New lists may be added
easily.

• SENTENCE FLASH — Much-the same as WORD

FLASH. In this case, 6000 grammatically-correct sen¬
tences are displayed (and, optionally, spoken). There
are also randomly selected grammatical questions
regarding the verb, verb tense, active and passive,
subject, subject sex, subject plural and subject singu-
lar, object, and punctuation marks._

• MUSIC — Four songs may be played through the
Apple's speaker, with the words shown on the screen.
The tempo is controlled by the paddle.

• MUSIC EDITOR — You may create your own tunes
and words. You may load, save, or play a song, add,
change, insert, or delete a note — easily! Notes range
over two octaves and can be full to 1/32 notes. Words
or syllables can be associated with each note.

• SCI-FI STORY — A nearly infinite variety of short
science fiction stories can be created and displayed.
The display speed is paddle controlled.

• TROUBLESHOOT — All of the question-and-answer
modules have the option to save the results (sta¬
tistics). The statistics include: number of presenta¬
tions, per cent errors, average response times, and
specific errors. These may be printed if desired. Also,
TROUBLE SHOOT will analyze the specific errors to
determine the possible perceptual or motor diffi¬
culties of: rotation, inversion, similarity, correct key/-
wrong hand, word truncation, word extrapolation, etc.

OTHER FEATURES

• You may choose to use upper- or lower-case letters.

• The character set may be changed (ASCII, Roman,
Collasal, and Flow are currently available; you may
also design your own font).

• The keys may be re-defined. The keyboard can be put
in ABC order instead of QWERTY.

• The 47-page manual is exceptionally clear.

ADVANTAGES

• PRIMER 83 is not an undirected drill-and-practice
program. It can be used to identify weak areas and to
strengthen skills in those areas.

• PRIMER 83 is aimed at the reading-impaired
audience. The instructions, prompts, etc., are de¬
signed to avoid frustrating the students. As many
cannot read, the manual is also supplied on cassette,
and voice prompts (ECHO II, optional) are available.

• PRIMER 83 allows the teacher to educate more effect¬
ively. Less time is spent administering exercises and
more time is available for analyzing the results and re¬
directing the student.

• PRIMER 83 blends in enough of the game reward to
make the exercises fun rather than boring.

Price: $99.95 Diskette

Paddles and ECHO II must be purchased separately.

PODGE in mind. Children love it, and learn, too!

HEALTH/NUTRITION

DIET ANALYZER

(IBM only)

Anyone who has ever tried to diet knows the problem-
count, count, count! Just keeping track of calories is a
monumental task. Did you ever stop to wonder about
the dozens of other nutrients, iike cholesterol, or
vitamins, that are usually forgotten?

The DIET ANALYZER makes it easy for you to review
and improve your eating habits. You simply enter foods
and it automatically shows you 24 nutrients for each
food and keeps running totals!

With DIET ANALYZER you can:

• Easily look up nutritional information about foods
and adjust that information based on portion sizes.

• Make intelligent menu planning a pleasure. Enter a
typical menu and see how it stacks up to what you
should be eating. Make a little adjustment here or
there until you get it right. Print menus on paper and
build a library of nutritionally balanced meals.

• Keep a log of the foods you eat. Periodically compare
your average daily intake of 24 nutrients with your
targeted goals.

As you insert, adjust, or delete foods in the Work Sheet,
all nutrients and totals are instantly and automatically
updated.

Foods are entered into the Work Sheet by name. Just
type in complete or partial food names and/or category
codes (e.g., vegetables), and the computer will display
all matching foods from the Food Dictionary.

The Work Sheet accepts a wide range of measuring
units for adjusting portion sizes. It allows special units
(e.g., a slice of bread, or an egg) as well as the usual
weight and volume measures.

Nutritional information may be displayed in physical
units (e.g., grams, milligrams, etc.) or as percent of
dietary goal.

The Food Dictionary is based on U.S. Dept, of Agri¬
culture tables, and contains many foods typically
consumed in American homes. It is easy to add, change,
or delete foods. You can add homemade foods by
entering their recipes.

SPECIFICATIONS

Nutrients listed in Food Dictionary—Calories, Protein,

HOME DOCTOR

(Commodore 64 and IBM only)

The usual approach to home diagnosis and treatment is
to use a layman's medical book to look up various
illnesses and see if the symptoms match your situation.
A doctor does not diagnose that way. He considers the
symptoms and uses a decision-tree approach to narrow
down the possibilities. That is basically how HOME
DOCTOR works. Although HOME DOCTOR does not
contain the vast wealth of information stored in a
physician's mind, it does have a disk full of information
pertaining to the more common maladies.

In our testing we found that HOME DOCTOR would
correctly diagnose gall bladder disease, inflamed
sinuses, food poisoning, etc. However, it failed to
identify Carpal-Tunnel Syndrome (it gave no diagnosis).
Then again, we checked a lay medical book and didn't
find it there either!

HOME DOCTOR works in two steps. First you choose a
general category from a scrolling alphabetical list of
problems (e.g., Abdomen, swollen). Then you are asked
a series of yes/no questions. If a diagnosis is deter¬
mined, you are then given advice as to a course of

HOME DOCTOR is not meant to serve as a replace¬
ment for professional medical help. However, if you
have small children, or if you or a family member is
sickly, it can give you some valuable advice very quickly
and inexpensively.

Excerpt from a review of:

DIET ANALYZER

(Reviewed by Michael S. Davidson, Creative Com¬
puting, March 1985)

"A very significant feature of this program is the Food
Dictionary. This database has nutritional information on
500 foods and, depending on your hardware, is
expandable to 1,900 foods. You can add, change, or
delete items. You can also enter any combination of
foods including home recipes, processed foods, and
entire meals into the dictionary.

“The program has a fully integrated set of instructions in
Help. Using Help will answer any questions about the
working of the program and is a highly expanded
version of the User's Guide.

“Overall, this superior program is extremely easy to use.
The data base is taken from a series of U.S. government
sources, and although the accompanying manual does
not indicate the credentials of the writers, the program
is professionally conceptualized and appears to have
been developed by health professionals. It provides the
serious diet analyzer with sufficient information to
determine his own course of dietary action. I can
recommend this program most highly.''

MYDIET

NUTRITION & DIET HELPER

(IBM only)

What should you eat to stay healthy? Are you getting too
much salt in your diet? Not enough fiber? Perhaps you
would like to lose a few pounds. Now you and your
family can use MYDIET to answer these and many more
questions about what you eat.

MYDIET creates your personal nutritional profile, based
on your height, weight, age, sex, daily activity, and the
food you eat. This profile lets you compare what you eat
to the Recommended Daily Allowances (RDA) which
are published by the US Food and Nutrition Board.
MYDIET clearly shows your nutrition excesses and
deficiencies and shows a bar chart comparing what you
eat to your RDA. In addition, it breaks down your food
energy to show the percentage of calories you are
getting from fat, protein, and carbohydrate.

You can also create a diet plan to gain or lose weight
over a specified period of time. Your diet plan is
displayed in a table which tells what your daily calorie
intake should be to lose or gain weight.

You can create nutritious meals and store your favorite
recipes. Each meal is broken down into its nutritional
value and stored in MYDIET's food list.

The foods, your diet plan, the RDA bar charts, and other
analysis reports can be listed on your screen or printer,
or stored on your disk.

MYDIET can be customized for your particular needs.
You can change your RDA values to meet your
nutritional needs and you can create a diet plan for your
dieting requirements. You can also customize the food
list by adding, changing, or deleting foods.

MYDIET is simple to use: all your choices are selected
from a list on the screen. Most entries can be made from
the numeric keypad. Even the foods are selected from a

menu. Built-in helpful messages tell you what to do if
you make a mistake. Pressing one key instantly brings
you back to the beginning from anywhere in the
program.

You can do the following with MYDIET:

• Track your daily intake of 24 vitamins, minerals, and
other nutrients.

• Create and store your favorite recipes, with a
nutrition breakdown.

• Print a table showing your nutrition deficiencies and
excesses over any period up to 60 days.

• Create a personal diet plan to lose or gain weight
over a specified period of time, based on your
height, weight, age, sex, and daily activity. Your diet
plan can be displayed on your screen or printer, or
stored on your disk.

• Customize your RDA values for particular needs.
MYDIET automatically adjusts the RDA values for
pregnant and nursing mothers.

• Calculate the percentage of RDA for the food you've
eaten, or any food or meal in the food list.

• Print a bar chart of the percentage of RDA on your
screen or printer, or store it on the disk.

• Print a table showing the percentage of your calories
derived from fat, protein, and carbohydrate.

• Store 60-days of diet and nutrition information for up
to 22 people (or 120 days for 11 people, etc.).

MYDIET has nutrition information on over 1,000 foods,
expandable to over 2,500. It even contains fast foods,
such as pizza, McDonald's hamburgers, tacos, etc. All of
the food quantities are shown in common units and
grams.

Up to 22 people can use a single MYDIET data disk to
store their personal diet and nutrition information. (For
more users, just make another copy of the MYDIET data
disk.)

TYPEMASTER

(TRS-80 only)

TYPEMASTER is a tutorial program for learning and
exercising touch-typing with the TRS-80 Model I or
III microcomputer. This program requires no
previous computer experience because only the
typewriter-like qualities of the microcomputer are
used. TYPEMASTER is very convenient for self-
instruction or for the classroom.

The program begins with an explanation of the
principles of touch-typing and a graph of the home
position of the fingers on the keyboard. The following
lessons familiarize the student with the positions of
the characters, drilling him or her in the use of the
correct fingers. Following these lessons you are
presented with achievement tests and drills in single
words that require either or both hands. The final
lessons are drills and tests in typing words and
sentences.

TYPE-RITER

(CP/M only)

Many computer users find that marginal typing skills
hamper their performance on the computer. With this
need in mind, TYPE-RITE# was designed to teach proper
technique and to improve the typist's speed and accu¬
racy through beginning and advanced timed and scored
practice. Menu driven, the program guides the user easily
through each step. Lessons are randomly generated—
producing 64,000 variations for maximum learning.
Scores are calculated in words per minute.

Although TYPE-RITER is a serious educational tool and
not a kid's game, it is fun to use, especially when users see
the progress they are making. All timed test scores can be
saved on disk by date and lesson number.

This automatic scorekeeping makes TYPE-RITER ideal for
personal or classroom use. This portion of the program
allows an individual or a teacher to record test scores on
disk by date for one typist or a group of students. Test
data is easily retrieved to the screen or the printer by a
teacher. Students can only look at their own scores.

TYPE-RITER's disk and detailed instruction book come
attractively packaged in a colorful, durable 6" x 9" plastic
dust-free container.

SCHOOL ATTENDANCE MANAGER

(TRS-80 and Apple only)

SCHOOL ATTENDANCE MANAGER (SAM) alleviates
the time consuming and endless chore of attendance
record keeping. This versatile, easy-to-use program will
automate the attendance needs of any size school. The
small-school version accommodates 800 students. The
large-school version stores data for 2,400.

SAM prints a daily absentee report, an individual
absentee record for any student, state-required monthly
attendance registers, homeroom lists, class rosters,
letters to parents, lists of students who have been absent
more than a specified number of days, and mailing
labiels.

SAM keeps track of absences, daily and cumulative
tardies, half days, religious absences, withdrawals, and
home instruction. All entries can be changed when
necessary and there is a provision for excused or un¬
excused absences or tardies.

SAM can display or print an individual student's attend¬
ance record or the entire school's. It will automatically
generate letters to parents of students who have been
out for a multiple of four days, and it will list all who have
been absent for two consecutive days.

The Master Disk File stores such essential data as student
names and addresses, birthdates, codes, telephone and
homeroom numbers, and sex. The program has a reset
feature so you can clear the disk of graduating students
and not have to re-enter the remainder of the school. A
clearly written guide leads the user through all phases of
the program's many useful features. The system requires
an Apple II+, lie, llc,oraTRS-80 Model I or III, plus two
disk drives and a printer.

TEACHER'S GRADE BOOK

(Apple, Atari,,[CP/M and IBM diskette only)

For each class in their master file, users of TEACHER'S
GRADEBOOK can store, retrieve, summarize, update or
otherwise manipulate and report extensive data pertain¬
ing to class administration, student rosters, grades, and
absences. To evaluate the performance of students, up
to seven distinct grade categories may be declared and
labelled for each class individually, and as many as 20
marks may be entered for each of those grade categories.
A separate file of absence records may also be maintained.

User applications vary considerably so it is impossible to
specify precisely how many records can be stored on any
one data diskette. For example, given the maximum
number of possible users on a single diskette (9), a
diskette would most likely be eventually filled by the
data pertaining to two classes of 35 students (each) for
each user. On the other hand, given three classes of 30
students each for each user, one data diskette should
accommodate five users; or given only one user, a
diskette will probably accommodate up to 15 small
classes or five very large classes of 90 students each.

TEACHER'S GRADEBOOK contains many features, inclu¬
ding password protection, easy data entry and retrieval,
versatile record structure, and much more.

TEACHER'S GRADEBOOK may be used with either one
or two disk drives, though twoare recommended. Minimum
RAM required is 48K. Printer output is optional. It is
never too soon or too late to automate your class record
keeping.

NOTE: The Apple version is single-user oriented. It
maintains grades for up to 12 classes with a maximum of
37 students per class. Price . $49.95 Diskette

SCHOOL DISCIPLINE MANAGER

(TRS-80 and Apple only)

SCHOOL DISCIPLINE MANAGER (SDM) keeps an accu¬
rate and up-to-date record of discipline information for
the Assistant Principal. The data can be entered easily for
each student and a running record can be kept to
facilitate monthly reports on discipline to the Board of
Education. *

SDM tracks 29 different infractions in up to 15 different
locations by a very simple coding system. It includes:

• dates of infraction

• type of infraction

• location of infraction

• teacher involved

• disposition

• administrator involved

The reports available include:

• A single student's entire discipline record. Inval¬

uable when several administrators have handled
different disciplinary incidents for a single
student.

• All infractions for a particular teacher.

• All infractions for an individual administrator.

• The number of each type of infraction. Permits

administrators to focus on their main problem or
problems.

• Two different monthly suspension reports:

A) names of all students.

B) number of students, broken down by sex.

• Preaddressed letters to parents

• Mailing labels

• Homeroom lists

• School or class rosters

Use SDM for parent conferences, in preparation for
court, or so your teachers can see hard evidence that their
complaints are being taken seriously.

This effective program will maintain the discipline
records for almost any size school. The small-school
version accommodates 800 students; the large-school
version 2,400 students. It is menu-driven and easily used
by first-time computer users. Thorough documentation
guides you every step of the way. The program has a reset
feature so you can clear the disk of graduating students
and not have to re-enter the remainder of the school.

CLASS RECORD

(IBM and CP/M only)

CLASS RECORD comes in two versions. The IBM version
can handle classes of up to 180 students; the CP/M
version, up to 36 students. Apart from this, both have the
same features.

CLASS RECORD can meet the requirements of teachers
at every level, from elementary through university.
Written by a university professor, it is the first program to
have the features and options which college classes
require.

Basic Features:

• Speed. CLASS RECORD was written in Turbo PASCAL
and is compiled for quick execution. It sorts 36 records in
about 2 seconds, 180 in about 6 seconds.

• Ease of use. CLASS RECORD is completely menu-
driven and can be run by persons with no previous
computer experience. The manual gives a complete step-
by-step explanation of every aspect.

• Automatically sorts and displays the names of stu¬
dents together with optional ID numbers and Credit/No
Credit (or Pass/Fail) status.

• Corrections are easily made through questions at the
bottom of the screen. The results are immediately dis¬
played. Further corrections or later corrections can be
made through menu items.

• Can record up to 10 assignments and 8 quizzes.

• Automatically converts marks (e.g., scales).

• Choice of grading systems. You can use either straight
letter grades or letter with 4- and —. You can set the
numerical range for each grade. You can also change the
symbols if desired (e.g., E, G, S, P, and U in place of A, B, C,
D, and F). This marking system can be saved on disk
under the teacher's initialsand called up for other classes.

• Print out records for:

- Any assignment or quiz.

- Any individual student.

- Complete record: assignments, quizzes, score,
mark, rank.

- Summary record: final score, mark, rank.

- Summary record: sorted by ID numbers in place of
names.

- Graph and statistics.

• Options for determining overall mark:

- Lowest assignment does not count: This is an option
chosen by many teachers who give manyassignments.
If this option is chosen, then all assignments have
equal weight, but quizzes, exams, or papers may be
assigned any weight. The program goes through each
student's record, drops the lowest assignment, and
then computes the mark with the weighting factors
assigned.

- All assignments count. You may have all assign¬
ments count equally or you may assign weights for
each.

• Print out all records for each student. CLASS RECORD
can print opt a separate page for each student listing the
markon every assignment or quiz, the overall score, mark,
rank. There is a place for further written comments. This
can be used at the end of the course. It can also be used
any time during the course. After mid-term exams, for
example, it is possible to give each student a summary of
the record to date and indicate the mark and class rank.
This is a convenient way of letting students know of failing
grades or missing assignments.

• All bookkeeping, scaling, etc., is done automatically.

• Any scores or grades determined by the computer can
be changed. The teacher ultimately assigns the marks,
not the computer.

• Posting marks. Teachers often want to post marks so
that students can know their grades quickly. Yet they also
wish to preserve secrecy. The program sorts records by ID
numbers. If the ID number contains 9 digits, the final one
is truncated. There is a legal reason for this. Many schools
use Social Security numbers as ID numbers. It is against
the law to post Social Security numbers.

• New Subject CLASS R ECOR D will make a copy of the
basic information on names, ID numbers, Pass/Fail status,
but not marks. This is designed for teachers who wish to
keep separate records of the same class for each subject
(e.g., elementary school).

• New Marking Period. This is designed for teachers
who need a new record for each report card period.

• Password Option. If the records are kept on a school
computer, then each person can have a password to
ensure privacy and security from tampering.

As you can see, CLASS RECORD has a fairly powerful set
of features. Also, it is very easy and convenient to use.

Requires two drives and 64K RAM (CP/M), 128K RAM
(IBM). CLASS RECORD does not require BASIC or any
other programming language.

CATALOG CARD AND LABEL WRITER

(IBM, Apple, C-64, TRS-80 Model 111/4 only)

CATALOG CARD & LABEL WRITER reduces the time
spent on this meticulous yet tedious chore. You input
the information when prompted, just once, and your
micro becomes a specialized word processor that
automatically formats and prints catalog cards and book
pockets and spine labels, as many copies as you need.
CATALOG CARD & LABEL WRITER provides individual
flexibility in card format while not sacrificing ease of
entering information. You can do hanging indentations,
long subject entries, and, if you have more information
than will fit on one card, it will do a second card. Author
or title main entry is provided for. The style followed is
based on Commonsense Cataloging by Piercy.

Even if you get the bulk of your cards with your books,
CATALOG CARD & LABEL WRITER will still pay its own
way for those additional subject cards, non-book
materials, and books you receive as gifts. It works well
with audio-visual materials and software. A variety of
catalog card formats can be used.

Aside from a standard 80-column printer and a single
disk drive, CATALOG CARD & LABEL WRITER requires
continuous-form cards and labels, sources for which are
listed in the documentation. A lower-case adapter (add
$30) is required for the Apple II+. Some IBM
compatibles require BASIC in the 40-column mode.

Price: $159.95 Diskette
Recommended by Booklist magazine.

Reviewer's comments ( Small Computers in Libraries
magazine):

"This procedure can produce a substantial savings in
staff time by removing the necessity to either type or
duplicate multiple card sets or to type added entries
onto duplicated or purchased card sets. There is also a
savings and convenience over the purchase of card sets
from off-site locations. Many librarians would see an
attractive benefit in being able to easily customize their
cataloging and not having to adapt their own cataloging
style to that of a card-production company or con¬
sortium ... documentation that is clearly understand¬
able and sufficient in quantity and detail... suitable for
librarians who are first-time microcomputer users."

MICROTEACH COURSEWARE
PACKAGE

(Atari only)

MICROTEACH is a courseware development package
designed to help the teacher prepare and administer
computerized mini-courses. To use this package you
(and the student) do not need to know how to program;
rather, you follow simple instructions.

The MICROTEACH system comes in three separate
modules which are on three disks.

TEACHER'S AIDE DEVELOPMENT MODULE

This module helps the teacher build a courseware disk
containing the desired lessons. You are supplied simple
graphics facilities and screen-editing functions to facili¬
tate lesson construction. In other words, you may build
and edit screens which have both graphics and text.

Each screen is numbered and the presentation (to the
student) is programmed. For example, there are several
types of questions available and, depending on the
student's response, the lesson is directed from the 'test'
screen to an 'answer* screen. This is ideal for programmed
learning or review exercises.

These question formats are available:

Multiple choice

True/False

Yes/No

Fill-in-the-blank

Matching

Programmed instruction

Page presentation time may be controlled, student
progress may be reviewed, etc. This module makes it very
easy to create a very substantial lesson.

EARN-IT/PLAY-IT

(Apple only)

EARN-IT/PLAY-IT is an automated "contingency manage¬
ment" program for classroom use; access to computer
games is contingent upon the student's behavior.

Each use of EARN-IT/PLAY-IT with a student is called a
session. Generally a session is one school day. The
teacher may identify up to nine objectives for each
student during a session (e.g., completes homework,
passes quiz, zero rate of misbehavior). At the end of a
session, the teacher records whether or not the student
has achieved each objective. If a specified proportion
(say 65%) of the objectives is achieved, the student is
rewarded with game credits. Game credits give the
student an opportunity to play one of the games con¬
tained on the EARN-IT/PLAY-IT disk. The student may
choose to save the game credit or use it immediately (if
the teacher permits). EARN-IT/PLAY-IT will keep track of
each student's game-credit balance. To maintain the
student's motivational level, new games become avail¬
able at certain milestones. There are six different games
on the DYNACOMP disk. At game time, the student can
select any available game for which he/she qualifies.
Naturally, the more interesting games cost more game
credits.

Requires 48K and one disk drive.

Price: $29.95 Diskette

Note: EARN-IT/PLAY-IT has been very successfully used
in a therapeutic program for rehabilitation (see COM¬
PUTERIZED REINFORCEMENT OF BEHAVIOR: A HEAD
INJURY CASE, Fifth International Symposium, Models
and Techniques of Cognitive Rehabilitation, Indianapolis,
Indiana, March 30 - April 3,1985. Maxwell, Dubin, and
Thompson).

STUDENT PAK MODULE

This module is used to run a courseware disk created by
the development module. It interprets the information
on the courseware disk and presents it as determined by
the teacher.

COURSEWARE MODULE

This is the lesson module created by the teacher. It is run
using the STUDENT PAK. Note that a minimum configur¬
ation is one DEVELOPMENT module and one STUDENT
PAK module and these modules are sold separately.
Teachers usually purchase just one DEVELOPMENT
module and a half-dozen or more STUDENT PAKs,
depending on their needs. Requires two disk drives.

MASTER DRILL

(TRS-80, Apple, C-64, CP/M, and IBM only)

MASTER DRILL is a utility specifically designed for
the educational environment With MASTER DRILL
you can quickly and easily set up multiple choice
drills on any subject you desire. All you do as the drill
creator is respond to the prompts. The program will
ask you for the question and its corresponding
answer. Later, when that question is presented to
the student, between two and nine (your choice)
multiple choice answers will be presented, one of
which is correct. The incorrect answers are drawn at
random from the answers to the other questions. For
those who have written multiple choice tests, you
know how much time this feature can save.

In addition, if your questions have a common
beginning phrase (e.g., "WHAT IS THE CAPITAL
OF"), you may pre-set this so that you need only
type the remainder of the question when prompted.
In this way files can be quickly built (and added to),
and very nice drills created. Included on the disk is a
sample drill called CAPITALS.

WORD PROBLEMS

(IBM only)

WORD PROBLEMS helps to improve problem-solving
skills. It presents a series of interesting stories. Each story
is made up of a sequence of challenging word problems
for a child to solve.

WORD PROBLEMS gains the child's interest by using an
animated character called "Tex the Tutor". Tex guides
the child one step at a time through the word problems
providing response and encouragement. This motivates
the child by showing that problem solving can be fun. It
also gives needed interaction which cannot be obtained
from conventional instructional materials.

The word problems presented are the result of extensive
research about specific skills necessary when solving
addition and subtraction word problems.

Features

• Controlled vocabulary (1.5-2.0 reading level)

• Interesting children's stories

• Reinforcement of important mathematical skills

• Instruction in regrouping skills needed to solve
addition and subtraction problems

• Emphasis on labeling skills to encourage critical
thinking

• Positive interaction with the childs's responses

WORD PROBLEMS takes full advantage of color graphics
to entertain and teach proper arithmetic skills. This
includes the graphic presentation of regrouping (i.e.,
borrow and carry).

WORD PROBLEMS is a solid educational aid to instruc¬
tors. It generates detailed statistics which evaluate the
child's performance. These statistics can help identify
specific problem areas in which the child is experiencing
difficulty (e.g., solving addition with carry). The program
is simple enough in function for home dse and is accom¬
panied by an extensive MANAGEMENT SYSTEM. The
MANAGEMENT SYSTEM allows a parent or instructor to
give specific, individual assignments to a child and
monitor progress. It is especially suited to the classroom
environment allowing an instructor to control a class of
up to 40 students.

Requires 128K, and a color graphics card. BASIC is not •
needed.

CAT (COMPUTER-AIDED-
TEACHING)

(TRS-80 only)

The CAT (Computer-Aided Teaching) package con¬
sists of two programs, CATGEN and CAT. CATCEN is
used by the teacher to create lesson, test and lesson
plan files. CAT is used by the student to run the
lessons and tests created by the teacher.

A lesson created by CATCEN consists of a screen of
mixed text and graphics, with an optional practice
question mode. In creating the lesson the keyboard
directional controls are used to place the cursor and
write mixed text and graphics.

The teacher may also enter up to 50 multiple choice
questions, with 5 possible answer selections for
each question. Automatic correction and scoring is
provided by CAT during the administration of the
test.

The lesson plan file creation procedure provides the
teacher with a method of automatically administering
a specific sequence of lessons and tests to the
student. The lesson plan consists of a chain of lesson
file and test file names, which will automatically be
:n by CAT when the lesson plan is entered.

Editing options are provided. Most commands are
menu-selected, and the operator is prompted for
most entries.

The CAT portion of the package provides the
operational environment for student use of the files
created by CATGEN. The student is prompted to
enter his/her name, the date, and the name of the
assignment. CAT automatically types the selected
assignment and proceeds to present the lesson or
test to the student. CAT provides correction and
scoring for practice questions and tests, and presents
the results and correct answers to the student. The
results may be optionally sent to the printer. Error
checking and trapping is provided to prevent
crashing the program through nonsense input.

If a lesson plan is loaded, CAT will automatically load
and run the lessons and tests contained in the plan.
Otherwise, the student must enter an assignment
name for each lesson and test.

COMPUTER AIDED TEACHING is flexible enough
to be used for every subject and grade level. It can
even be used in business and industry for training.
Includes a detailed manual. Requires 48K. Printer

ME ET YOU RSELF is a guide that takes you on an extensive
tour of the less well charted regions of your own psyche.
It will help you discover new and unsuspected aspects of
your personality. As your individual character portrait
unfolds, your problems will be discussed and set against
the background of some of the wider issues of life. These
may bear upon your case or throw light on questions of
general interest and significance beyond your immediate
personal concern.

The format used is a mixture of questions and observa¬
tions. The package consists of over 200 blocks of rou¬
tines, not all of which are used in the analysis of any one
individual. Each routine acts in conjunction with a per¬
sonal text file that you will set up in the second disk drive.
From the information that is stored in the text file and the
answers to the questions, you will be guided to further
questions or observations (not always kind!) about your
personality.

MEET YOURSELF requires 48K of RAM, and two disk
drives. It comes on five diskettes.

CP/M-MS DOS TEACHING
TESTING AND TRAINING PROGRAM

(CP/M and IBM only)

The most important first step in acquiring computer
literacy is to learn how to use your computer's operating
system. For CP/M and MS DOS machines, this is no
mean feat!

The 3T package was designed to be a school in itself,
simulating the classroom environment. There are text
lessons, multiple-choice questions, and coaching. Test
scores are used to direct the student backwards or
forwards in the lessons.

Many prominent computer trade journals have evalu¬
ated 3T and found it to be one of the most successful
simulations of a school format.

3T was designed and programmed by Software
Academy and is used in its computer school. If you are a
beginner to CP/M or MS DOS, become our student!

PC CHORD PRIMER™

(IBM only) '

The PC CHORD PRIMER™ is a package of software
programs for the IBM Personal Computer that are
designed to provide interactive assistance to the serious
guitarist The program capabilities range from a built-in
library of over 600 chords to a set of automated lessons
on music theory for guitar.

The program is divided into two major components. One
consists of educational programs that include lessons on
general chord structure and chord progression patterns.
The other serves as a computerized reference manual or
handbook. It provides a chord encyclopedia that auto¬
matically searches for chords by name or musical key,
programs to assist music composition and transposition,
and a guitar tuner.

This computer-assisted guitar tutorial has several advan¬
tages over standard reference books.

1. Many of the programs provide audio support
through the PC's music synthesizer. This allows the user
to hear as well as see the relationships between notes and
chords.

2. The program automatically searches its chord data
base to find chord positions. This reduces the time
normally spent flipping through reference manuals.

3. By letting the computer perform chord transpo¬
sitions the user can avoid referring to complicated chord
tables and transposition formulae.

4. The program utilizes printer support so that hard
copy reference material can be generated instantly if
needed.

5. Screen graphics are fully used.

Requires an IBM with DOS 1.1, 64K memory, the IBM
graphics board, color or monochrome monitor, and one
disk drive. A printer is supported but not necessary.

your own BASIC or machine-langauage programs. SDS
exploits amost every aspect of the C64/128's sound
capabilities.

SDS has a variety of applications. Use it as a
programming tool or as a learning aid (for those wishing
to simply experiment with sound and music). Create
your own instruments, or use some of the example
instruments provided. Any sound you can imagine can
be created with ease and speed. Develop multi-
instrument songs or simple sound effects. SDS even
provides an option to view the sound data (for the more
advanced users).

The fully detailed manual, along with examples, takes
you through each step, clearly and simply. You do not
need to know music to use SDS, though the effects you
can produce do improve with your experience level.

Includes a 50-page manual. A printer is supported but is
not necessary.

MUSIC BY MATRIX

(Commodore 64 only)

Music has changed more in the last 50 years than in all the
time prior. Methods of teaching music have hardly
changed at all in the last 300 years. MUSIC BY MATRIX is
designed to bring the music student up to date.

The single most important concept a music student must
understand is interval theory. There are ai number of
chords and scales that the student must learn. This is not a
small task; it becomes much larger when the student tries
to transpose these chords and scales into all 12 keys. The
MUSIC BY MATRIX system is designed as an audio-visual
aid to help the student understand chords and scales in
terms of the intervals involved. This one factor can take
years off the time that it takes to teach the basic com¬
ponents of music theory.

In summary, the matrix system is designed to make it
easier for the music student to learn basic music theory.
The matrix system is not designed to teach standard
music notation, nor to replace it. To get the most out of
the program, the user should know how to read and write
music, at least at a basic level. The student who knows
how to read simple songs is ready for this program.

MUSIC BY MATRIX is also written for music hobbyists
who have no desire to learn how to read and write music.
It includes two experimental music generators that offer
an easy way to access the sound and music capabilities of
the Commodore. By simply typing a couple of numbers,
you can listen to a large variety of computer-generated
music. For the musician who composes, the matrix is
shown to be an excellent format for writing modern
music.

MUSIC BY MATRIX also explains the seven modes.
Understanding how these modes are formed and used is
very important to improvisation, harmony, and melody. A
sound generator is included that allows the creation of
music based on traditional harmonies. It is a very simple
way to use the computer to compose.

Finally, MUSIC BY MATRIX lets the user experiment with
mathematical tonalities. There is a short explanation of
how our Western music system differs from Eastern
music. The matrix is used to generate a wide range of
experimental tonalities; it is also very simple to use.

Price: $29.95 Diskette

MUSIC BY MATRIX, DISK #2

(Commodore 64 only)

Disk #2 picks up where Disk #1 ends, with five
programs, the first being TRIADS.

TRIADS explains the diminished triad and the dimin¬
ished chord, and shows their relationship to the simple
cycles. Most musicians have heard of the Cycle of
Fifths, and some of them know that it is the inverse of
the Cycle of Fourths. Very few musicians know about
the remaining simple cycles and how they are used. The
augmented and suspended fourth triads are also
detailed in TRIADS, and tests are included for all 3
triads to help you gauge your progress.

The next program on Disk #2 fully explains the matrix
with a series of examples. The simple cycles are covered
in detail, and the matrices illustrate how they are
related. Interval theory is introduced in a manner that is
easy to understand and a table of intervals is included
that will be a useful addition to any musician's library. A
music generator is provided to allow you to experiment
with the tonalities of the simple cycles.

MELODY BY MATRIX (the third program) introduces
the concept of using the matrix to work with existing
melodies. The melody line to Mary Had a Little Lamb is
placed on the Y axis of a series of matrices, and the X
axes vary. Selection of the music generator offers many

THE SOUND LIBRARY

(Apple only)

THE SOUND LIBRARY is designed to aid programmers
in using sounds. It comes with 39 prepared sounds and
explains how to produce your own effects.

THE SOUND LIBRARY is divided into two basic parts.
The first consists of the library of sounds and their
parameters (in BASIC). The other serves as the sound
generator (in machine language) for the library.

All of the sound routines are menu-selected and are
easy to understand.

With THE SOUND LIBRARY you can generate whole,
half, quarter, or eighth notes as well as unique sounds.
You may freely copy the routines from the library to add
to your own sound programs!

Price: $19.95 Diskette

options. The melody and/or the X axis of the 30 and 45
degree diagonals may be listened to in various
combinations. Some of the tonalities are really
astounding.

For the composer, the possibilities are myriad. The
matrices contain an infinite amount of related har¬
monies, any of which might be the basis for a piece.
Some sound good enough to use exactly as they are;
others must be altered to the composer's taste.

The fourth program, MUSIC BY NUMBER, offers a
unique experimental music generator. Songs can be
written simply by typing numbers for the notes.
(Anyone can easily learn to enter songs from sheet
music, and the person who doesn't read music might
end up learning to as a bonus.) The melody is then
placed on the Y axis of the a matrix; sound selection
offers any combination of the melody and the 30 or 45
degree diagonals. Imagine harmonizing your songs with
the diagonals of a matrix!

The last program is a tutorial on the pentatonic scales.
Beginning with a short review of some of the materials
covered on both disks, the section goes on to discuss
briefly some of the methods by which many "standards"
have been written.

You can save the songs that you (or the computer) write
to disk. A number of songs are provided to get you
started. The notes in the melody and the diagonals can
be printed (on the screen) for analysis. Compositions
can be played over and over again on a group of
matrices; this is ideal for serial harmonization and
composition.

In summary, MUSIC BY MATRIX, Disk #2, is a valuable
addition to any music student's library, and for any
computer hobbyist who enjoys music.

FAST FOURIER TRANSFORM
TUTORIAL

(Apple, Kaypro, and IBM only)

FAST FOURIER TRANSFORM TURORIAL is a menu
driven, graphics oriented education program designed
for both class room use and self-instruction. The
program itself presumes no knowledge of the
mathematics associated with Fourier Transforms.
Rather, it permits hands-on experience showing (in
high resolution) what the spectra of various waveforms
look like. For example, you may examine the spectra
of mixed sinusoidal, rectangular, saw tooth, triangular
and random inputs under an infinite variety of
conditions. You may even input your own signal.
Further, you may examine the spectra of several
window functions and digital transmission formats.

The resulting spectra may be plotted as well as
listed. It should be stressed that FFTT is an educational
program, which is highly tutorial in character. It does
not have the data storage, retrieval and editing
features of DYNACOMP's HARMONIC ANALYZER.
However, if you want to get a feeling for Fourier
Transforms, or already have some knowledge and
want to learn more, this is a good program to use.

Requires 48K. Includes a manual which describes in
some detail the mathematics of the FFT. Included on
the DYNACOMP disk are an Applesoft and a
compiled object program.

DIGITAL FILTER DESIGN TUTORIAL

(Apple only)

This is the third member in DYNACOMP's complex
plane analysis series. In DFDT the subjects of trans¬
versal, comb and interpolation filters are theoretically
discussed (in the manual) with several examples.
Windowing (Bartlett, Kaiser, Gauss, raised cosine,
etc.) is considered, along with practical approxima¬
tions to ideal filters.

The software portion of this package is very easy to
use and is keyed to the theory in the manual. You
may examine the design of filters from several
different aspects. For comb and interpolation filters
you may graphically (high-resolution) look at the
amplitude and phase response of a variety of transfer
functions underan infinity of coefficient conditions.
For transversal filters you can graphically and
numerically look at the coefficients associated with
many standard types of filters, and truncate/window
the resulting series coefficients to examine the
practical effect on the filter response. You can even
multiplewindow. In addition, you can input your
own amplitude response coefficients and truncate/

Z-TRANSFORM TUTORIAL

(Apple only)

This is the second selection in DYNACOMP's
complex plane analysis educational series, the first
being FAST FOURIER TRANSFORM TUTORIAL. In
Z-TRANSFORM TUTORIAL poles and zeroes and
their relation to the Z-transform are described theo¬
retically (in the manual). The resulting filter response
function is discussed with respect to rational poly¬
nomials and "tapped delay lines". The tapped delay
line representation is shown to be amenable to a
"difference equation" implementation of a digital
filter.

The software is keyed to the manual. You may enter
either the pole/zero representation, or the rational
polynomial filter function coefficients for up to 30
poles and zeroes. If you give the poles and zeroes,
the program calculates the transfer function. If you
give the transfer function, the program will give you
the poles and zeroes. Also, you are provided with
high resolution plots of the amplitude response and
impulse and step function responses. Several
examples are given.

the development of analog filters through the use of
pole/zero representations. Subjects covered include
the narrow and broad band approximations, the unit
circle, the Butterworth, Chebychevand linear phase
solutions.

The second part of the package, the software, allows
the determination of complex poles and zeroes and
graphical examination of the frequency responses
associated with the material in the manual. You may
analyze the responses due to the poles/zeroes
which you provide, or determine the poles/zeroes
and responses for various order Butterworth,
Chebychev and Thompson filters. The variety is
infinite, and emphasis is placed on graphical displays.

TWO-PORT ANALYSIS TUTORIAL

(Apple only)

Here it is — number seven in DYNACOMP's electrical
engineering tutorial series. This analysis package allows
you to learn about and examine the transfer characteris¬
tics of "black boxes" having two ports (four terminals).
For example, a transistor may be considered a four-
terminal device if the base is used for two of the terminals
(e.g., common base configuration). The device descrip¬
tion used is based on Y-parameters.

The manual has two sections. The first deals with the
theory behind Y-parameter descriptions and response
stability. The second part deals with computer examples,
in particular the design of a transistor amplifier having
several RLC components.

As with the other packages in this series, the software is
graphics-oriented. The equivalent circuit is pictorially
displayed on the screen, as well as the G L circle cor¬
responding to the stability limit. Also superimposed are
the B^ circles.

This package is ideal for the student or professional who
is studying linear systems. Price: $24.95 Diskette

INVERSE FAST FOURIER
TRANSFORM TUTORIAL

(Apple only)

INVERSE FAST FOURIER TRANSFORM TUTORIAL (IFFT)
is an educational program which was designed to be used
by teachers and students to familiarize themselves with
the IFFT and its effect on transforms. It is also useful to
engineers and scientists who wish to learn about the IFFT,
its operation, and the general ability to reconstruct
signals (time functions) from their discrete Fourier trans¬
forms.

The documentation is broken into two parts. The first part
deals with the theory of the Fourier transform pair in
general, the discrete Fourier transform (DFT), the Fast
Fourier transform (FFT), and frequency domain filtering.
Many graphical examples are included throughout.

One of the unique features of I FFT is that it aiso contains a
routine which shows the distortion of serial (e.g., NRZ)
transmissions by a telephone line. You specify the length
of the line and the baud rate, and the program graphically
displays the distorted bit pattern. Also shown are the
"eye patterns" used by communications engineers to
evaluate such transmission lines.

The second part relates to operating the program. To run
the program, just follow the prompts. You can specify
various standard signals (or your own) and the sampling
interval. Up to 128 points may be specified (or loaded

BILINEAR TRANSFORM TUTORIAL

(Apple only)

Here is number five in the advanced electrical
engineering tutorial series. This one deals with the

MCI 648, phase detectors, AFC, hold-in range, etc. The
program part allows you to experiment with building a
phase-locked loop from phase-detector, low-pass filter,
and VCO blocks. You may simulate TV synchronization (a
picture of Kirchoff may be "played with") and examine
hold-in and lock-in both visually and analytically. Of
particular interest are the effects caused by the use of
various filters and filter functions.

FREQUENCY DOMAIN
FILTERING TUTORIAL

(Apple only)

FREQUENCY DOMAIN FILTERING TUTORIAL (FDFT) is
DYNACOMP's ninth installment in its growing engineer¬
ing tutorial series. This particular addition is an extension
of FAST FOURIER TRANSFORM TUTORIAL to two
dimenensions.

As usual, the package consists of two parts; the manual
and the program diskette. The manual describes the
theory behind the two-dimensional discrete Fourier
Transform along with pictorial illustrations (3-D repre¬
sentations are included). You may then visually examine
the results of transforming and filtering various two-
dimensional patterns (including bars, sine waves, good
old Kirchoff, etc.). The results are displayed as either a
spectrum density plot (picture) or a 3-D representation.
You may choose from a menu of ideal filters, or input your
own. You may choose images from the menu, or create
your own.

Because the calcualtions involved are so time consuming,
you are provided two versions of the calculation program:
a compiled version (default) and a source (Applesoft)
version for examination. Also, instructions are given
regarding how to generate your own images. You may also
load images from other programs in the DYNACOMP
engineering tutorial collection.

Requirements: 48K RAM, one disk drive, and some initial
familiarity with Fourier Transforms. FDFT is an ideal tool
for advanced image students, photographic science stu¬

covered in the manual.

The subject areas included are: autocorrelation, power
and energy spectra, cross-correlation, cross-spectral
density, convolutions, and matched filters. The computer
examples include correlation (e.g., burst correlation, a
means for radar ranging) and two-dimensional template
matching. Many variations are offered in the examples

PORTFOLIO MANAGEMENT

COMPUSEC PORTFOLIO MANAGER

(Apple only)

Except for modem downloading of stock data, the
COMPUSEC PORTFOLIO MANAGER does everything
that the DOW JONES Market Manager does, and more
(but for a much lower price!).

Here are some of the COMPUSEC advantages over
DOW JONES:

• Ranks each stock in any portfolio, showing which
stocks should be reduced or eliminated, and which
should be increased.

• Calculates for any stock, the compound growth rate
between the earnings-per-share for an earlier time
period and the earnings-per-share for a later time
period.

• Calculates the payback period (years to earn back
the market price), based on the calculated growth rate
or your own estimated growth rate.

• Shows daily volume.

• Automatically records date and time when quotes
were fetched.

• Shows unrealized gains and losses with subtotals:
short term gain, short term loss, net short term, long
term gain, long term loss, net long term, as well as
combined total net gain or loss.

• Shows analogous helpful breakdown for realized
capital gains and losses.

• Shows number of securities held as well as total
number of shares held.

• Shows average cost per share for total holdings of
each security, as well as average cost per share for each
separate holding.

• Permits entering exact costs (including cents). Also
permits entry of securities costing less than $1.00.

• Requires only one disk for both program and
portfolios, though additional portfolios may be re¬
corded on additional disks.

• Requires only one disk drive.

• Permits viewing or printing of all reports, and hence
does not require a printer.

• Provides for automatic adjustment of cash figure
when:

1) purchases and sales of securities are made

2) additions to, and withdrawls from, cash are made

3) a mistake is made and a reversal of a sale has to
be made

FUNDWATCH

(IBM only)

FUNDWATCH is an easy-to-use, menu-driverf tool
created to simplify evaluation and comparison of
various common investments including mutual funds,
stocks, bonds, and many commodities such as energy
and precious metals. FUNDWATCH is designed to
allow home investors to seriously evaluate such
investments inexpensively and quickly without re¬
quiring a modem or a costly data network subscription.
Although especially suited for the fast-growing market
of mutual funds, FUNDWATCH can be used to evaluate
virtually any type of capital growth or income oriented
instrument, including market averages such as the Dow
Jones Industrial Average.

FUNDWATCH conveniently:

• Calculates yields.

• Predicts annual yields.

• Evaluates trends (using variable moving averages;
you choose the trend period).

• Creates comparative graphs depicting normalized
performances.

• Provides direct comparisons with interest-earning
investments.

• Maintains basic portfolio information.

• Permits giving each portfolio a full name (such as
John Q. Investor).

• Subtotals net capital gains and losses for each
security, even when different lots are sold on different
dates. This greatly simplifies tax return preparation.

Quite frankly, the review (12/83, SOFTALK Magazine ) of
the DOW JONES package served as good guidance on
how to make a far superior product!

Includes a 100-page manual. A printer is supported, but
is not required.

Price: $79.95 Diskette

Sample printouts:

You may evaluate up to 17 funds per database (there is
no limit to the number of databases). Share prices for
each fund are conveniently entered on a weekly basis.
Dividends and share distributions are entered as they
occur and FUNDWATCH automatically adjusts the
database to reveal actual resulting performance.

FUNDWATCH comes with a 38-page manual explaining
its uses in detail and which clarifies concepts for
beginning investors.

Requires 128K of RAM, DOS 2.0 (or higher), and a
graphics card. A graphics printer is necessary if you want
printed plots.

frequency you desire. In addition to writing files to
maintain historical records of those prices, STOCK
MASTER will maintain files of the Dow Jones I ndustrial
Index, the Standard and Poor 500 Index, and the
NASDAQ Index at the same frequency.

• Calculate "trailing Price/Earnings ratios for any stock
for which you have entered quarterly earnings data for
at least the last four quarters.

• Display the value of any of the portfolios you are
maintaining using the most recently entered price for
each stock

• Plot graphs of the price history of any stock vs. any
other or vs. on the Indexes. Axes are automatically
scaled and labeled on the hires screen. Hard copies
may be readily obtained by either dumping directly to
a printer or to a disk and then to a printer of your choice
in a later step. Data can be plotted for the last 3,6 or 12
months.

• List the historical price record of any stock or portfolio.

• Plot the historical value of any portfolio as a percent of
the first value plotted.

• Alter portfolios at any time and, if desired, maintain a
cash balance for each portfolio.

STOCK MASTER/STOCK PLOT requires 48K of RAM, can
operate with one or (preferably) two drives, and can print

STOCK MARKET BARGAINS

(IBM only)

After more than 40 years of successful application by
many individual investors and mutual funds, the intrinsic
value theories of Benjamin Graham have been pro¬
grammed for use on the IBM (and compatible) personal
computers.

STOCK MARKET BARGAINS provides two tests for cate¬
gorizing, evaluating, and storing statistics on stocks con¬
sidered under-valued ... and ripe for purchase by the
shrewd investor.

Test I — The Graham Approach

The first test is based on theories Benjamin Graham set
forth in his landmark books Security Analysis and The
Intelligent Investor. In this test, a stock's investment
value is "graded" by its Quick Liquidation Value.

This value indicates what would be distributed to each
share of stock should a company pay all its short- and
long-term debts out of current assets and distribute the
remaining current assets to shareholders. If this projected
distribution amount substantially exceeds the stock's
present market value, the stock is considered to be
selling at a bargain price.

For example, a stock with a market price of $6 per share
and Quick Liquidation Value of $10 per share is, more
often than not, a bargain-priced investment. Using
STOCK MARKET BARGAINS, you can identify these
stocks.

Test II — Pre-set Values You Can Change as Needed

While the Graham approach exemplified in Test I can
lead to some excellent bargains, it is not always possible
to find a large number of stocks satisfying these criteria.
Because of this, a second, less stringent approach to
identifying undervalued stocks is provided in Test II of
STOCK MARKET BARGAINS.

Test 11 evaluates stocks according to five parameters—all
programmed with pre-set values. In contrast to Test I
however, Test II selection parameters may be altered to
your specifications.

Test II Parameters:

• Price/Earnings Ratio

• Number of Institutional Investors

• Ratio of Current Assets to Current Liabilities

• Change in Earnings per Share

• Current Earnings per Share

Four of these five parameters are designed to ferret out
those companies exhibiting healthy cash positions and
favorable price levels regardless of the product or service
a company provides. The fifth parameter, number of
institutional investors, is a measure of obscurity designed
to find companies that haven't been extensively scrutin¬
ized by professional analysts.

These companies may not have attracted the attention of
the large institutional investor either because the com¬
panies are too new or too small. In either case, such
stocks are fertile hunting ground for undiscovered bar¬
gains.

STOCK MARKET BARGAINS is menu-driven and allows
you to:

• Display and/or print out all stocks satisfying Test I and
Test II

• Display complete data on tile about any given stock

• Add new stocks for analysis at any time

• Update the data for stocks already in your computer's
data files

You are given guidelines that will enable you to enter the
necessary data from the Stock Guide quickly and effi¬
ciently.

PORTFOLIO STATUS

(IBM only)

PORTFOLIO STATUS provides a convenient means for
generating timely analyses of security portfolios for the
individual investor or the investment advisor. The user
enters the name of each security, the ticker symbol (if
desired), the number of shares, the purchase date, and
the cost. To generate an analysis of the portfolio, the user
enters the price of each security and the program pro¬
ceeds to compute the current market value, profit or loss,
percent profit, and days since purchase for each security,
and then to compute totals.

The program is completely menu driven and, in so far as
possible, checks are provided to catch obvious input
errors such as mistyping a date (e.g., 06/08/1084 for
06/08/1984). If a new portfolio is to be entered, the first
question asked is for its name. When the user supplies a
name, he/she is asked to enter the data on as many
securities as are in the portfolio. When that is completed,
a menu is presented asking whether there are to be
additions, deletions, or changes, or whether records are
to be examined, or the status of the portfolio is to be
computed. Additional menus are provided at each step
so no knowledge of computers is required to run the
program.

The results are presented in alphabetical order and may
be displayed in 80-column format on the screen or in
132-column format on a printer. Requires 64K.

CASH FLOW PROJECTION

(Apple only)

CASH FLOW PROJECTION is designed to provide a
quick method for estimating future cash flow (before
income tax) which may be generated by producing oil
and gas leases for their remaining economic life.

Future production of the primary phase is calculated
using the exponential-decline method. Up to three dif¬
ferent exponential-decline segments may be used to
calculate each lease projection, in order to approximate
hyperbolic-type declines. It is much easier to break a
hyperbolic-decline curve into three exponential seg¬
ments than to determine the correct components of the
hyperbolic curve. A yearly exponential-decline rate,
beginning monthly production rate, and an ending
monthly production rate are entered for each segment. If
more than one decline segment is entered, the ending
monthly rate signals a cutoff point for production rate
calculations at that decline rate. The second decline
segment is then used and finally the third segment is used
to calculate projected oil and gas production. Whether
one, two, or three segments are used, the last segment
will be used for calculations until a negative cash flow
calculation has been performed. The secondary phase is
calculated from a gas-oil ratio.

The program generates a printed report giving the input
assumptions, gross oil and gas production, net oil and gas
production, oil and gas prices (which may be escalated
each year to a stipulated cutoff price), net oil and gas
revenue, net operating expense (which may be escalated
each year to a stipulated cutoff amount), net severance
taxes, net windfall profits tax, net salvage value, net
before income tax yearly and cumulative cash flow, net
before income tax yearly and cumulative discounted
cash flow, and net before income tax cumulative dis¬
counted cash flow for four alternate discount rates. All
five discount rates are selected by the user.

Individual projections may be totaled and a composite
projection report may be printed out giving the com¬
bined results.

features which make it unique among the investment
software available today. These features include:

• the same data editing, maintenance, printing and

price adjustments as MSP.

• stock price charts with:

price range, range and close, or close
prices transformed by:
moving average
centered moving average
exponential smoothing
inverse of any price transform as a bar chart

constant-width envelope for either centered moving

average or exponential smoothing.

• volume bar chart.

• smoothed volume line.

• up to 3 stock price or volume charts overlaid on a

chart.

• smoothed velocity (price change) line.

• on balance volume, using percent price change.

• support for printers from 31 to 223 columns per line.

MCP can use the system you have to the fullest. Addi¬
tional memory and storage allow larger price/volume f iles
to be created and used. A wider printer allows more
complex charts to be generated.

INVESTING ADVISOR

(TRS-80 and IBM only)

THE INVESTING ADVISOR is a tool that will help the
investor make unemotional decisions about the buying
and selling of his investments. It incorporates a means of
timing the purchase and sale of investments based on a
price-trend analysis and on buy/sell rules. It includes the
ability to track both long- and short-term trends, so that
the i nvestor can pick the best strategy for his needs. U p to
64 long-term and 64 short-term investments can be
tracked at the same time. The investor can initialize his
data base, add or delete investments, calculate the action
to take and adjust the data base for splits of the invest¬
ment. Data is entered daily for short-term investments
and is entered weekly for long-term investments. The
data entered is the closing price for the investment,
available from the newspaper. It is in the form of the price
as it appears in the paper.

The objective of the long-term investment strategy is to
go over a year, if possible, without selling. The selling
rules provide a reasonable compromise between the
desire to go long-term and the need to protect profits or
to prevent substantial losses, if the investment turns
down significantly. The objective of the short-term in¬
vestment strategy is to maximize capital gains without
regard to the tax consequences of selling. The selling
rules provide a compromise between giving the invest¬
ment room to maneuver as it moves up and the need to
protect profits or to prevent substantial losses, if the
investment turns down.

The program has been written to be as structured as
possible. The logical levels of the program have been
indented so that the user can understand the flow of the
programs, if he desires. Requires 48K.

and/or short positions in overvalued puts and calls, can
be surprisingly safe and profitable. Combinations with
over 95% chance of profit are not uncommon.

The first program in the software package computes
normal (theoretical) values, differences from actual
prices, and implied volatilities for the options on a
stock. This is what you need for picking candidates for
your spreads.

The main program, Options Hedging, lets you examine
the prospects of spreads and combinations. You can
determine the best ratios among the options, and find
the probability as well as the magnitude of future profit.
Gain curves are presented both in graphic and tabular
form, and for any selected future date. Round-trip
commision and margin requirements are calculated,
and net profit tables are printed.

Because option prices fluctuate around the normal
values, the profit in any hedge position varies from day
to day. A third program is included to let the investor
follow the progress on a daily basis. It takes only a
minute to input the latest stock and option prices and
get a printout showing the profit if the position is closed
that day.

The manual consists of two parts: first, a valuable
introduction to option terms and general advice;
second, a demonstration of the use of the program with
typical examples.

The CALCUGRAM STOCK OPTION SYSTEM has been
in use for several years with remarkable results. Here are
the comments of one user

/ can't tell you how much I appreciate your
Calcugram option program. It is not only educational
but I am actually making more money now in option
hedging than I have ever made in any kind of
investment even when I used a broker.

For the first time in my life I feel comfortable with
combination hedges.

Requirements: 32K (TRS-80) or 64K (IBM), two disk
drives, an 80-column printer, a color graphics board
(IBM); (optional).

EXCERPTS
from a review of
BUYSEL

(by Brian Greiner, Software Now!, April 1985)

"The manual consists of thirty-five pages ... It is well
written, and explains every aspect of the program fairly
completely. One section I particularly appreciated, was a
'walk-through' of all the various features using sample
data files to show how the program worked. The manual
explains in detail the parameters used by each trading
method, and gives some detailed background informa¬
tion for each method. There is also a brief bibliography of
books the program's author found useful.

In use, Buysel is rather a lot of fun.... I used the supplied
data files to analyze a sample stock and commodity with
no problem.... Buysel is useful not only for picking the
best investment strategy for a particular stock, but also
useful for weeding out the dogs.... The program seems
reasonably crash-proof and easy to use.

Overall, Buysel seems like a useful tool for people inter¬
ested in the stock market. It offers the user a number of
different trading methods to choose from, and is fairly
simple to use.

MICROCOMPUTER BOND
PROGRAM

(available for all computers)
MICROCOMPUTER BOND PROGRAM is designed
to help you evaluate bonds. It provides a quick and
easy way to estimate the prices and yields of fixed
income securities under a broad range of assumptions
and estimates about the future.

The price of a bond depends upon several factors
including the risk of the issue, the interest it pays, the
date it matures (or is subject to early call), the
general level of interest in the market, and the
expectations of the market for the future course of
interest rates. The yield of a bond is influenced by
the investor's tax rate, by the length of time the bond
is held, and of course, by the price paid for the
securities.

While MBP cannot help you predict the future, it can
surely show you the results of any combination of
circumstances you predict on the price of a fixed
income security. And knowing that, you can make
better decisions concerning the issues you invest in.

MBP provides:

Complete bond data entry, editing, listing and
storage capabilities.

A flexible analysis environment, including
market interest levels and tax rates.

Bond yields before maturity, showing estimated
price, total dividends, and gross yield.

Bond prices estimated over time, at various
market interest rates, evaluated to either maturity or
early call.

Bond valuations, showing current yield, and
before and after tax yield to maturity.

With MBP, the questions you have concerning the
future performance of bonds can be answered
quickly, easily, and with a minimum of work.

THE VERSABUSINE8S* SERIES

(All computers except Atari, C-64, and TRS-80 Model I)

For some time now DYNACOMP's research staff has
been looking for a complete and coordinated accounting
system available at a reasonable price. We believe we
have found it in the VERSABUSINESS™ SERIES produced
by Computronics. Many of you may already be familiar
with this software; it has been heavily advertised in
national magazines for the past year. With the addition of
the new VERSALEDCER IT, this series is one of the best
available (see the reviews).

DYNACOMP's relationship with Computronics has been
exceptionally good. For the past twoyears Computronics
has been advertising and distributing DYNACOMP
products with considerable success. Now it's DYNA¬
COMP's chance to return the compliment. (Note that we
offer Computronics software at discount prices.)

Note: Apple versions require two disk drives. _

(•bout VersaRecelvablee 2.0)

“I would like to compliment you on the accomplishment

of the above program.stuffed with elegant features

which, of course, I do not have to tell you about. What I
can tell you about is which ones, I, as the end-user,
appreciate the most: the possibility for the user (without
any programming knowledge at all) to enter into the
program the printer codes for changing the print pitch

prior to report writing.(and) the possibility of isolating

the transactions of a user-defined group of customers
(by account number) within a user-defined period of time
(by date). This allows an easy distribution of sales
commissions to the different sales reps by month, week,

or any other period of time.I could go on and on,

describing the terrifi features of this program.

$99.95 — may be exactly what you need. VersaPayroll
handles weekly, bi-weekly, semi-monthly, and monthly
periods. The program can print out all payroll checks and

SMALL BUSINESS INVOICER

(IBM only)

SBI has been designed especially for small businesses
and is particularly suited to the following situations:

• Your invoices must show a lot of detail about what
you bill — typically one or two pages.

• No two invoices are alike; some are long, some are
short, and the content of each is not repeated.

• In addition to your time, you also bill for other things,
such as out-of-pocket expenses, parts, or cost of goods.

• You want to customize each invoice, not force it to
fit within a rigidly structured billing program.

• You want a system that is easy to learn and easy to
use.

SBI was designed for businesses which charge for both
time and expenses, work on a project basis, and need to
show considerable itemized detail on their invoices. SBI
is aimed at first-time computer users who need a
friendly program that can also perform a task that is
immediately useful to them.

• Variable-length formats

• Variable-content formats

• Menu-driven

• Full editing

• Job indexing

• 70-page manual.

• Very easy to use

The editing screens are particularly nice and contain
work boxes, etc.

BOOKKEEP

(CP/M CBASIC only)

BOOKKEEP is a general ledger and financial state¬

business use. It has a high degree of flexibility and is
meant to be used by someone who has a strong
familiarity with bookkeeping. BOOKKEEP will permit
you to enter transactions, prepare formal financial
statements, query account balances, close the
books, prepare statements by company segment,
and printout both ledgers and journals. The program
employs a double entry bookkeeping system and
can be used either on the cash (tax) basis or accrual
basis.

The major account categories covered are current
assets, property/plant/equipment, current assets,
debt, equity, revenues, cost of sales, R and D, selling
expenses, administration expenses and "other".
Each of these categories is further broken down into
several subcategories.

BOOKKEEP runs under CBASIC (which comes with
many machines, such as the Osborne-1), and requires
a printer, 56K.

DECISION ANALYSIS

(CP/M and IBM only)

DECISION ANALYSIS will not make decisions for you,
but it will help you better organize your choices and the
factors involved, and, in turn, help you make better
decisions.

DECISION ANALYSIS sees to it that you define the
choices and criteria clearly, and supply ratings. Then it
analyzes your ratings to show how each choice compares
with all the others. The analysis is presented in three
tables of paired comparisons:

• fable of advantages: How much the choices outscore
each other.

• Table of Disadvantages: How much the choices are
outscored by each other.

• Table of Best Choices: Which choices are superior to
the others.

What you do is simple. You enter your choices, criteria,
and levels of confidence. There are several options,
including the weighting system, confidence levels, date
printing, saving, etc.

DECISION ANALYSIS may be used as both a tool and as a
training aid. To the latter end, a clearly written manual has
been prepared which takes you step-by-step through an
analysis session and includes helpful commentary.

Requires at least 48K and one disk drive; a printer is
supported, but optional. MBASIC release 5.2 or higher
(BASIC-80) is needed.

JOBMASTER

(TRS-80 and IBM only)

JOBMASTER is designed for supervisors, managers,
and engineers who are responsible for managing
small production and assembly programs. Typical
examples would include machine shops, sheet
metal shops, mechanical assembly areas, and
electronic assembly areas. Practically any business
involved in manufacturing or assembling a product
can make use of JOBMASTER.

The JOBMASTER program allows the user to set up a
data file describing each individual operation in the
shop area, including the station, contract or project,
task name and description, date, employee name
and I.D., and shift Also included is a cost breakdown
which includes labor, material, and work station
costs, as well as hours worked, projected production
and actual production. Full data file editing capability
is provided, as well as a very useful automatic
updating command which provides easy data file
maintenance and permits changes and updates to
the data file to be made with great rapidity.

In operation, the program provides full sorting and
searching capabilities, allowing the file to be sorted
by any data category, as well as limited and global
searching for keyword matches. Both text and
numeric data may be searched and sorted.

A major feature of the program is the file evaluation
command. This command can be used to compute
costs and man-hours in a variety of ways. As an
example, computation can take place on a station-
by-station basis, a contract-by-contract basis, an
employee-by-employee basis, or a date-by-date
basis. In fact, the evaluation can be keyed to any of
eight possible data categories. Costing information
is provided on an item by item basis, as well as being
totalized by category item.

The evaluation function features a pre-sort option,
which allows the file to be sorted by a user selected
category prior to the actual evaluation. This feature,
along with the category selection options of the
evaluation, provide a great selection of choices with
regard to data presentation and evaluation results
(approximately 64 variations).

JOBMASTER also provides a schedule generating
feature. By appropriate selection of category, 8
different types of schedules can be created, such as
a day-by-day schedule, contract-by contract schedule,
employee-by-employee schedule, and so forth.
Another feature of the JOBMASTER program is the
ability to generate cash flow/man loading projections.
Again, a number of options are provided to generate
cash flow based on a number of possible categories,
including contract-by-contract and day-by-day
projections.

JOBMASTER'S versatility lies in its ability to evaluate
and output the contents of the data file in a number
Of different ways, providing the user with a maximum
amount of data in a user-selected format The user is
thus provided with rapid access to vital information
to aid in the scheduling, planning, and control
functions of the production area
JOBMASTER operates as a user-friendly program,
providing menu-driven commands and prompts for
all data inputs. Several convenience and data-verifi-
cation features are also incorporated into the
program to provide for ease of use. Error-trapping is
provided to prevent data loss in the event of disk
errors or similiar problems.

CONTRACTOR MANAGEMENT
PROGRAM

(TRS-80 only)

The CONTRACTOR MANAGEMENT PROGRAM
(CMP) is a management tool designed to assist
general contractors and related businesses in the
processes of estimating, planning, scheduling, and
controlling of the contracting business. The program
has a large menu of functions which provide the user
with cost, scheduling, and resource utilization
information in a wide variety of formats.

In operation, the CMP provides for setting up of four
data files containing information on equipment,
personnel, materials, and contracted services. Each
entry in each file contains information defining the
name, site, location, task, function, cost, and
scheduling of the item. Employee entries provide for
overtime and doubletime considerations.

Utilizing the data files, the program provides standard
searching and sorting functions, and supports multi¬
file chain operations.

An evaluation command provides the user with a
number of options for evaluating cost. The entire file
may be processed, or individual entries may be
selected and processed. The evaluation command
also includes a powerful category evaluation option,
which allows the user to figure costs for all unique
entries within a category. As an example, a file
containing 30 entries for 6 dump trucks, covering 5
different sites and time periods for each truck,
would result in the generation of 6 printouts,
covering a complete cost evaluation for all entries
pertaining to each truck. This command can be
performed on a wide variety of categories, providing
cost and utilization breakdowns in a large number of
convenient formats.

CMP also includes a tracking command. This
command allows the user to generate specialized
data dumps by any data category. As an example, a
printout can be generated to provide schedules for
each piece of equipment or employee. Or a printout
can be made to show activities at each work site, or
to show resources assigned to each task. The track
command operations on a number of data categories,
providing the user with convenient and useful data
in a wide range of possible formats.

CMP is a user-friendly, menu-driven program which
prompts for each required input. Error-trapping is
provided to prevent data loss in the event of DISK
FULL and similiar errors. Line printer output is
supported, and is recommended for several of the
program functions. Pagination and screen control is
included to provide neat, easy-to-read printouts.

CMP includes data verification routines for data
inputs and provides full data file editing capabilities.
Additionally, a useful updating command is included
to allow any data category to be rapidly updated
without editing the entire item. This functioh is

PROJECT CONTROL ONE

(TRS-80 and IBM only)

PCI is a basic project control and scheduling
program designed for engineers, managers, builders,
and other supervisory personnel who have respon¬
sibility for project management. The program
provides numerous options and capabilities for
obtaining a maximum amount of useful information
with a minimum amount of input data. The program
does not require the use of CPM or PERT techniques,
(or familiarity with them) and was designed for
projects whose size and nature do not necessitate a
rigorous application of these methods. The program
provides user-friendly menu selections for the
command functions, and supports hard-copy output
as well as C RT display. A printer is highly recommended,
as the printed task/event charts and percent complete
charts are printer-only functions. Both 80 and 132
column printers are supported, including selectable
density types. Price: $49 95 Diskette

NOTE: The IBM version requires 128K of RAM, a
parallel printer port, and two double-sided floppy
drives (or one double-sided drive and a hard disk).

SKILLS INVENTORY

(IBM only)

SKILLS INVENTORY is a database program written
specifically for employment agencies, contract pro¬
gramming companies, and personnel departments of
companies wishing to maintain a file of job candidates
and their associated characteristics.

Once information about prospective candidates is
entered, specific job requirements can be specified,
and the database searched for candidates who meet
those requirements.

The following information is recorded:

• Education.

• Willingness to travel.

• Willingness to relocate.

• Defined search criteria: Up to 300 skills or other
search parameters can be entered, with up to
eighteen assigned to each candidate. Each of the
assigned skills can also have one of the following
experience levels assigned to it:

1. Training only.

2. Light experience.

3. Medium experience.

4. Heavy experience.

5. Experience not applicable.

These same characteristics are used for candidate
searches.

The Candidate File includes such information as the
candidate's current position, work phone, home phone,
a record of interviews, the account executive assigned
to the candidate, and two user-defined fields, in
addition to the job characteristics mentioned above.

Other features include:

• A built-in word processor which allows you to type in
letters, print them immediately for specific candidates,
or save them on disk for later mass printing for selected
candidates.

• The ability to print name and address labels for
selected candidates in ZIP Code sequence.

• Menu-driven, with on-screen help information.

• There are no skill codes to memorize; you simply
enter the descriptions.

EASY RECORDS II

(Atari and IBM only)

EASY RECORDS II is an easy-to-use, yet powerful finan¬
cial records keeping package for the Atari family of
computers.

Up to 55 tracking files may be created (e.g., an expense
track, receipt track, etc.). You are also provided with a
"net-to-date" file of expenses and receipts, a separate
depreciable item expense track, and several special
function keys to retrieve the most often used infor¬
mation. For example, pressing the "=" key will bring up
the year-to-date figures for expenses, receipts, and net.

You can also have a hard copy of all files on a monthly or
yearly basis. For example, on the expense file report, the
check number, date, amount, purpose, and payee will be
reported.

Each data disk can hold 300 transactions (minimum), and
data can be carried over from disk to disk; the amount of
storage is unlimited.

EASY RECORDS II has been carefully designed to be
"user friendly". It is menu driven and error trapped. The
manual is clear (it even includes quizzes!). Also supplied
is a training disk for learning the basics.

A common concern expressed by those new to compu¬
ters is the difficulty in creating the initial records required
to set up EASY RECORDS II for their particular business
(since EASY RECORDS II is so flexible, you must define
some of the functions, formats, etc.). The authors have
responded by providing assistance in the form of data
entry templates which greatly simplify computerizing
your existing records.

To sum up, EASY RECORDS II is flexible, easy to learn,
easy to use, and inexpensive.

Requires 48K, and one disk drive. Supports a printer (not
required, but recommended).

Price: $59.95 two Diskettes

The IBM version requires DOS 2.0 (or higher), BASICA,
two drives, and 128K of RAM.

INVENTORY CONTROL

(IBM only)

If you are concerned about popular items being out of
stock, how much money is tied up in inventory, or
inventory records showing goods that aren't even in
stock, then you should try INVENTORY CONTROL

INVENTORY CONTROL will allow you to value all
inventory items at either the average cost or the last
price paid. It will sort into descending order and print
the total inventory value. In addition, besides the
normal functions of adding and deleting on-hand
amounts, INVENTORY CONTROL will give you the
option of printing summary information for all parts of
the system, or detailed information on a selected part
basis.

Other features include the option to print a historical
report showing the usage or sales for all parts over the
past 12 months on a month-by-month basis. This could
show you trends or seasonality factors. This report also
indicates the total usage over the past 12 months for
each part and sorts the data in descending order of use
or sales to show yoq fast and slow sellers.

A reorder report is also available. It prints those items
whose on-hand amount is equal to or less than the
established reorder level for that part. Pricing infor¬
mation for each part can be displayed through a series
of price reports based either on average cost, last price
paid, or current selling price. These price reports can be
sorted according to your needs.

You are allowed, in most fields, either numeric or alpha
information. For example, if you did not know the
amount received three months ago, you could enter NA
rather than a numeric amount. Another nice feature is
that you are given the option (in most cases) either to
send the report to your terminal for display, send it to
your printer for a hard copy, or both.

The documentation includes a complete set of program
listings for those who may wish to customize the
package.

System requirements include an IBM PC, 128K of
memory, DOS 1.1 or above, two disk drives, and an 80-
column printer. With single-sided disk drives the system
capacity is 650 parts.

VIDEO RENTAL MANAGEMENT
SYSTEM

(IBM only)

If a club member came into your store to rent a movie,
would you know immediately how many past-due tapes
that member has in his posession? Or, if a member came
to you and said that he or she had just seen
"Manhattan" and wanted to see other movies that
Woody Allen has directed and starred in, would you be
able to quickly provide a list?

INVENTORY MANAGEMENT
SYSTEM

(TRS-80 Model 111/4)

The INVENTORY MANAGEMENT SYSTEM provides you
with effective and economical inventory control. It is
designed for use in small to medium sized companies.
IMS improves service, reduces costs, and increases
profit potentials. It is appropriate for situations in which
it is important to know what is in inventory, but is not
intended for cases involving high turnover of numerous
low priced items. Ideal applications include furniture
and appliance stores, or small businesses handling only
a few hundred products.

IMS includes proven inventory analyzation methods,
generates reports for inventory decisions, and assists in
profit planning. In addition to determining your pur¬
chasing needs, IMS shows profit potentials, sales
transaction summaries, inventory evaluation, and parts-
on-order information. One unique feature is a method
that determines whether the overhead cost of main¬
taining an item in inventory is more than its potential
profit (time for a close-out sale?). The goal of IMS is to
maximize your profits!

• Updates'the inventory based on current period
transactions.

• Summarizes revenues and quantities of sales, orders
placed, and goods received.

• Details current purchasing needs.

• Calculates potential profit based on inventory,
overhead, and expected sales.

• Shows the number of periods of supply that the
current inventory level represents.

• Evaluates inventory wholesale costs, retail values,
and cost of goods on order.

• Provides sales forecasting.

• Highlights parts currently overstocked.

Typical parts data stored are part number, vendor part
number, description, cost/unit, price/unit, quantity in
stock, sales rate, desired inventory level, on-order
quantity, order date, vendor code, etc. Included is a
very carefully prepared, "user friendly" manual (60
pages).

Requires at least 48K of RAM, an 80-column (or wider)
printer, and two disk drives.

office phone numbers (including area codes), and a
one-line comment You have flexibility in setting both
the address "field" widths as well as label width (one-up
or two-up labels) and spacing. Labels can be printed
alphabetically by name, by selected city or state, by area
code, or in ZIP Code order. Multiple labels for a
selected person can also be printed.

Phone numbers may be easily found by choosing an
alphabetical letter in the database, and "paging"
through the entries starting with that letter.

Extensive use is made of cursor positioning to make
data entry and editing fast and easy, as well as simple to
learn. Includes a 36-page manual which discusses all
options and gives examples (you probably won't even
need this manual!).

EXECUTIVE PHONE/MAILER requires 128K of RAM,

CLIENT/SALES MASTER

(IBM only)

CLIENT/SALES MASTER is one of the most useful and
powerful tools available to you Here are several good
reasons why you should use CLIENT/SALES MASTER:

• Track your clients and prospective clients.

• Easily maintain client/customer list

• Print mailing labels (one to four across).

• Compiled programs for super-fast performance.

• Assign as many as 40 different classes or types to each
address or person that you have defined.

• Unlimited number of files or addresses (limited only
by available disk space).

• Print all reports and labels in either alpha sequence or
by ZIP Code.

• Select the addresses to be used by 40 different codes
or address types defined by you.

• Menu driven for easy learning and for easy use.

• Hard copy (a report) of your clients/customers.

• Have a report or labels printed based on certain

Example 1: You are an automobile dealer and you would
like a report of all your repeat used-car clients that do not
use your service department You would also like to have
mailing labels for a service promotion you will be having
for these people. And, of course, you want a report and
labels for your service customers that did not buy their
auto from you.

It would also be nice if you could have a list of all your
customers for a specific salesman and specific type of
automobile.

Example 2: You are the sales manager for a manufactur¬
ing company and you need a list of all clients of a specific
salesman. You need monthly reports of your customers
printed by the sales territory that your salesman will be
(or should be) calling on.

Example 3: As the manager of an employment agency,
you have an employer on the phone who wants to know
(right now) if you have any prospective employees that
are willing to relocate, have a degree in engineering, and
had a G.PA of over 3.50.

qualifications (e.g., name, address, city, state, ZIP, and
any of 40 different classifications).

• Display this information immediately on your com¬
puter screen: search.

• Have mailing labels printed for your client/customer
promotions including selections based on types or
qualifications.

• Allow for duplicate names and addresses.

• Use 10-digit ZIP Codes.

• Browse through the address file (either forward or
backward).

• Print address lists either complete or abbreviated.

• Use with either diskette or hard disk or both.

• Capture the company name or title of the individual
which prints on the labels or reports).

• All searches and print selections can be global (i.e.,
you can find all customers with the last name begin¬
ning with the letter "D" in all ZIP Codes beginning
with "50".

Example 4: As the personnel manager, you need a report
of all your employees who have a review date coming up
during the next month. You also need reports that show
which employees have life insurance, which ones can
operate an adding machine, and all employees over the
age of fifty (and who have not used any sick time in the
last six months).

Example 5: As a not-for-profit organization, which of your
contributors gave during the last year to your fund for
hunger; who gave over one thousand dollars; and who
gave over five thousand; and, perhaps most important,
which contributors didn't fit into these catagories? Of
course you need the labels for mailing.

CLIENT/SALES MASTER can do all of the above. What is
your application?

Requires DOS 2.0 or higher, a printer, and 128K of RAM.

A 20-page manual is included.

PERSONAL PRODUCTIVITY

PERSONAL TASK MANAGER

(IBM only)

The PERSONAL TASK MANAGER is a personal task
organizer and time-management tool for the person who
needs to get more done in less time.

At its most basic level. PTM allows you to enter your most
important "Things To Do Today"; to rank in order of
priority; to sort according to ranks; to save in a file; and to
display the list on a printer. You may (optionally) list the
estimated time that each task should take and the
projected starting time; the finishing time will be auto¬
matically calculated and displayed.

Should tasks or priorities change, you may recall the
original list to the screen and add or delete items, change
priorities, or alter the time estimates. Similarly, on the
following day, a new list may be generated from scratch or
by modifying the previous day's list.

For long range planning, PTM allows you to generate, sort,
save, and print "Future Tasks" lists with optional pro¬
jected starting and/or finishing dates.

PTM is useful to anyone who needs a convenient way to
organize daily (and long-range) tasks, prioritize them, and
to estimate, schedule, and control the amount of time
each task takes. Since PTM may be used to organize the
activites of one or many individuals, it should be particu¬
larly useful to supervisors, professionals, students, home¬
makers, and other task-oriented individuals.

PTM has been designed to allow quick throughput with
maximum flexibility. Easy-to-read screens, automatic
help messages, and clear option and error messages
make PTM essentially self-documenting. However, a
complete illustrated user's manual is provided to guar¬
antee, ease of use for the novice as well as the exper¬
ienced computer user. Furthermore, the 35-page User's
Guide provides a brief, helpful discussion of time man¬
agement principles.

Requires 96 K of RAM, at least one disk drive, and a
printer. Does not require BASIC.

ADAM

AUTOMATIC DECISION ASSISTANCE
MANAGER

(Atari only)

ADAM is not a game. Rather, it can help you make logical
decisions about almost any kind of problem.

ADAM is based upon the classical management decision
grid. This popular conceptual tool facilitates decision
making involving many conflicting elements. With ADAM
you can center your thinking on the issues involved and
how you feel about each one of them. The computer
takes care of the mathematics. It even calculates a level of
confidence for its suggestions.

Three different versions of ADAM are provided. One is
written in Atari BASIC, another in Microsoft BASIC, and a
third uses both Atari BASIC and "SAM", the software
speech synthesizer. You must have a copy of "SAM" to
use the features of this third program.

The ADAM manual describes each step of this easy-to-
use program. There is also an appendix which explains
some of the similarities and differences between Atari
and Microsoft BASIC.

No computer prbgram can insure that every choice you
make will be the right one. However, if you accept
ADAM's help, at least you will know that your decision
was based upon a good examination and comparison of
the issues.

(Apple, IBM, and Commodore 64 only)

MIND PROBER is one of several Human Edge Software
personal-interaction analysis packages which have
received quite a bit of publicity in the news media.
These packages are designed to help executives relate
to, get along with, and even manipulate those with
whom they must deal daily.

MIND PROBER works by asking specific questions;
then it prepares a report. Infoworld reviewed it and said:

IMIND PROBER] promises to make 1984 a reality.
They tried to analyze Ronald Reagan, with the following
results (an excerpt):

Mr. R. R. is driven more than others to be
around people. He often thinks about being
the center of attention, or being important to
others. This person would love to be an actor, a
politician, or something else that would give
him center stage and national prominence.

While he may get angry quickly, Mr. R. R. can
become upset by conflicts with other people.
When he gets into an argument, you can
expect him to end up apologizing for his short
fuse. Open agression usually bothers him. He
would rather give in to an adversary than
behave in a socially improper way and
potentially damage his reputation.

MIND PROBER will help you to:

• Understand why someone behaves as he does.

• Accurately predict what someone will do in a given
situation.

• Learn to interpret another's nonverbal clues.

• Discover the things most people are afraid to tell you
about themselves.

• Have a scientifically accurate personality profile of
anyone—in minutes.

• Sharpen your perceptions and communication style.
In addition, MIND PROBER is quick and easy to use.

KEEP TRACK OF IT

(CP/M only)

Many middle and upper income families have pur¬
chased a computer with the idea that it would help
them keep track of their financial records. However, the
idea has often remained an idea because the available
programs took hours to set up and were slow in
execution. Now there is a very fast and very easy
solution.

KEEP TRACK OF IT (KTOI) is a budget program that can
be set up in two hours by a computer novice. It
organizes your finances and gives you a printer net-
worth statement each month that shows all your assets
and your liabilities. It also presents a monthly report of
income and expenditures by category. A similar report
can be generated for the year to date.

KTOI can handle up to 210 accounts (or categories of
expenses and income). There can be up to 210
checking (or savings) accounts. For example, you and
your spouse may have checking accounts, charge
accounts, business accounts, savings accounts, IRA
accounts, certificates of deposit, money market ac¬
counts, and other family members may have their own
accounts.

The transactions can be marked for later selective
recovery based on tax or other factors of your choice. At
the end of the year the program will prepare a disk for
the next year's data and will carry the balances in each
account to the new year.

This program is not written in BASIC and executes very
quickly. For example, it takes less than a minute to find
the last transaction in over 1,700 transactions.

You can find each transaction (and edit it if you want) by
the date, the amount, the memo, who it was to or from,
or the accounts it affects.

No knowledge of accounting is needed and no
knowledge of computers is necessary. When each
transaction is entered; the computer shows you the
effect on your finances, and clearly prompts you for the
next operation.

Requires 48K, 80-column printer (or wider) and two
disk drives.

LOAN ANALYSIS

(Atari only)

In today's marketplace with sky-high interest rates and
several different lending facilities to chose from, it is
important to have at your disposal every scrap of infor¬
mation possible in order to make the most intelligent
decisions about borrowing. This program is written to
aid you in making the best possible choice when it
comes time to borrow and to arm you with the facts
about interest rates, payment schedules, and amortiz¬
ation of loans. This program will provide you with those
options before you sit down with your lending facility.

The program is divided into three parts. Each part if
available by making a choice from the menu. The firs
part allows you to vary the amount of the loan, interest
rates, and the life of the loan. The second part gives you
the option of determining how much you might save if
you pay a little on your loan each month. It will show
you the differences in interest paid, amount of total
payments, and equity created. The third part will
amortize your loan and show you month-byrmonth how
your repayment schedule works and why the cost of
borrowing money is as great as it is. LOAN ANALYSIS is a
small investment which can save you much.

Requires 16K (cassette), 24K (diskette).

BUDGET MODEL ANALYZER

(Atari and Commodore 64 only)

BUDGET MODEL ANALYZER (BMA) is a unique
financial-planning tool designed to provide you with a
clear and revealing picture of your overall cash flow
situation. It is easy to use and does not require
cumbersom record keeping, yet it can show you a great
deal about your spending habits and spending capacity.

To use BMA you need only provide a list of all your various
incomes and expenses. Each income and expense must
be described as being per day, work day, week, 2 weeks,
month, quarter, or year. BMA uses these period
specifications to correctly weight each income expense.
BMA provides you with a very convenient maintenance
system for creating, saving, and altering your list (or lists).

BMA can then expand your list into a complete matrix
that shows each item in your list, expressed in each of the
various period specifications (day, work day, week, etc.).
It shows you the result of all your incomes and expenses.

For those who do not fully appreciate numbers, BMA will
produce a bar graph giving a graphic representation of
your budget.

BMA allows you to compare expenses occurring in
varying frequencies. Is your $ 5.00/work day lunch really
worth $ 109/month when you consider what that amount
could do for you if you applied it to a house or car
payment?

Even more useful is the ability to see clearly the result of
all your incomes and expenses. How much extra
spending capacity do you have?

THE HOMEOWNER

(IBM only)

THE HOMEOWNER can help owners of single homes
(who do repairs and renovations themselves) and
owners of rental property (who do repairs and
maintenance on a regular basis to several properties)
save money and be better organized.

THE HOMEOWNER is menu-driven, which makes it
very easy to use You need only select options from
menus and enter data when prompted. There are no
command sequences to learn. Very little knowledge of
computers is required to use THE HOMEOWNER, and
there are even tutorials.

THE HOMEOWNER provides several powerful and
cost-saving functions:

• A data manager which helps you maintain accurate
records of repair and renovation costs. It automatic¬
ally computes sales tax and total cost (including
labor) for a project and summarizes cost figures for
projects. This part of the program is especially
helpful at tax time. It is also a good way to keep track
of fix-up costs if you are preparing a property for sale.

• A report generator which permits you to list or print
both materials lists and project summaries. A unique
feature of THE HOMEOWNER is the provision for
printing a quotation form. This form allows you to
enter and print required materials and descriptive
information .for use in obtaining quotes from
suppliers or contractor. The quotation form also
makes a shopping list.

• A materials estimator which helps you estimate re¬
quired quantities of many repair and renovation
materials. (No need to search for that high school
math book to find the formula for cubic yards). This
part of THE HOMEOWNER also provides you with
required quantities of items needed to install or
attach the material.

• An energy-saving estimator which projects energy
savings from many improvements (heating day/
cooling hour tables included). This part of the
program also figures the playback period for energy¬
saving improvements. Includes energy calculations
for storm window, caulking, insulation, etc., R-value
heat loss calculations.

Includes a 120-page reference manual and a tutorial
that will help you become familiar with all the parts of
THE HOMEOWNER.

THE HOMEOWNER requires an IBM-PC or PCjr (or
compatible), 128K of RAM and one 160KB diskette
drive. Will run on 40-column or 80-column displays.

PERSONAL FINANCE MANAGER

(Apple, CP/M, and IBM only)

PERSONAL FINANCE MANAGER (PFM) is designed to
run under Microsoft BASIC (Release 5.2 or higher for
CP/M; Applesoft BASIC for Apple) using any CP/M
operating system. PFM includes all of the features of
DYNACOMP's popular PERSONAL FINANCE SYSTEM,
and has several more for those individuals with more
complicated and extensive financial records.

PFM requires one or two disk drives and can store
approximately 3,600 records on a single double-density
5V«" diskette. Up to four savings accounts and four
checking accounts can be simultaneously maintained,
with the balance in each account automatically dis¬
played when in the menu mode. There is also a "cash"
account.

All transactions may be flagged for later sorting. The three
standard codes are taxable/non-taxable, checking/
savings/cash, and deposit/withdrawl. There are also 26
user-defined codes.

Each of the checking accounts can be balanced sepa¬
rately. PFM sorts through the chosen account to find
entries that had not cleared the bank at the time of the
previous balance, and then asks if they have now cleared.
The record of any transaction that has not cleared can be
dumped to a printer if desired. The balance routine also
has an edit feature to allow for direct editing while
balancing the account.

A separate edit routine also exists to allow the user to edit
any records that are in the data file. An individual account
can be keyed or all records can be viewed starting with
the most recent, scanning forward or backward as
desired. As an added convenience, it is possible to jump
to a specific record number if desired.

A sort routine has been included to allow the user to sort
for specific records by selecting among six sort para¬
meters. This can be done in several different ways. After
the sort has been completed, a list of all the records can
be printed, along with a summary including a graphic
display for the year.

The sorting/searching/merging available in PFM is very
flexible. For example, you may sort alphabetically, or by
check number, category, etc. When searching, you may
use "and" or "or" tests between categories (for example,
collect entries corresponding to checking account#1
AND which are taxable OR which are written to a
particular person). You have to use this capability to really
appreciate its power!

PERSONAL FINANCE MANAGER requires one diskdrive
and a machine having at least 48K. A printer (80 columns
or wider) is supported, but not required.

DATABASE MANAGEMENT

FILES

(IBM only)

FILES provides all the integrated software tools the
typical professional, manager, or entrepreneur needs to
work quickly and efficiently. The program features the
following:

It's a DATABASE MANAGER

You can create, edit, save, retrieve, and perform data-
management operations on relational data-base files.
The basic storage unit is a file with similar files stored
together.

It's a SPREADSHEET

Any data-base file can be treated as a spreadsheet. Values
are referred to by using friendly names such as EARN¬
INGS PER SHAR E. Spreadsheet and database features are
united in a common language. You can define the for¬
mulae, relationships, and equations in one file while the
data used is located in another file. You can edit either
file, then recalculate the spread sheet at any time with a
single command. To permit complex or iterative pro¬
gramming, you can automatically record and repeat any
command sequence (a very nice feature!).

It's a WORD PROCESSOR

FI LES lets you create word processing files. You can insert,
delete, revise, center, indent, move to or from a buffer,
relocate, highlight for bold or underline printing, mark
page starts, find, replace, scroll up, scroll down, page up,
page down, etc. Features such as word wrap, right
justification, margin, width, page length, and spacing are
also supported.

Data files and word-processing files can be converted
from one format to the other. You can also treat lines of
word processing documents as spreadsheet entries.

It's a CALCULATOR

Standard financial computations such as present value,
future value, annuity, loan, and depreciation are sup¬
ported.

It's a REPORT GENERATOR

FILES will automatically generate a letter-quality report
with headers and page numbers for either data files or
word-processing files. You have the option of printing
data files from top to bottom or from left to right. Details
such as page and document totals are computed auto¬
matically.

Rather than having to write a procedure to display your
data, it is always shown in a format based on the current
settings of the format parameters (such as margin).

It's a GRAPHICS GENERATOR

You can view the data as records in rows or columns
simply by changing the display mode. You may also see
your data in stacked or separated bar charts. The cursor
keys permit you to scroll through the graphs one at a time
or from left to right. It's exactly like scrolling around in a
large spreadsheet except the entire display is graphical.
Other modes permit normal, composite, percentage,
composite percentage, or log plots. The bars are auto¬
matically labelled and scaled. Text mode graphic char¬
acters permit operation with any display or printer.
Special commands permit placing graphs within data¬
base files.

It provides TRENDING

You may compute the regression line relating several
columns of data using any of 5 standard equation types.
The resultant equation (or any user-defined equation)
can be usedto calculate an expected-value field. You can
also compute the correlation coefficient, standard error
of the estimate, multiple correlation coefficients, expo¬
nentially smooth data, moving averages, or interpolate
between two values.

It provides STATISTICS

Using the statistics menu, you can perform most of the
standard statistical tests of hypotheses, analysis of
variance, or you can look up statistical distribution values.

It's a CRITICAL-PATH MODEL GENERATOR

You may determine a schedule of early-start, late-start,
early-finish, and late-finish dates along with float given a
task list with duration, beginning, and ending-node data.
You can also add a time plot to see the schedule.

You can edit BASIC programs or assembly-language
source code using the word processor. You can transfer
ASCII files in or out You can convert from almost any
units to any other units. You can display the sum, average,
etc., of the entire file. You can store multiple files in
memory and manipulate them just as you would data in a
calculator.

But most of all. ITS INTEGRATED

All files of all types fit together in a common master list of
relations. Once you set the margin, spacing, or any format
value, the value acts in the logical way on graphs and
data-file displays.

And, IT'S EASY TO USE

In addition to the HELP menus, there is a good User's
Manual and a tutorial for beginners. The current file and
command menu are always displayed and you can scroll
or page in any direction to the desired position in any file
in the data base. Instead of an unwieldy spreadsheet the
data is organized in logical packets or files, with all files

DATA RETRIEVAL SYSTEM (DR8)

(CP/M, Commodore 64, and Atari only)

DATA RETRIEVAL SYSTEM (DRS) is a fast cross-indexing
system which may be used to store and retrieve infor¬
mation according to key words. Although DRS was origi¬
nally set up to index journal articles, it can be used
equally well to cross-index record collections, recipe
files, etc.

In the CP/M version you can conditionally search (e.g.,
BYTE, 1984, CRYPTOGRAPHY) byupto4 key words. You
can assign your conditional key-word search to any
combination of fields (columns). The result of your
search can be sent to the printer or screen. Also, you may
include numeric data fields and conditionally sum them
(e.g., a mini-expense system). In addition, you can
establish an ALERT flagging system which prints a mes¬
sage when certain conditions are met (e.g., you have
made more than three payments to a particular person in
1984). The CP/M version of DRS is more than a system to
index journal articles; it is a versatile and flexible data
management system.

The Atari version is set up more as a traditional indexing
system. You can search on key words in the title (key
words can be appended to the title). However, the length
of the article description is unlimited.

Both the CP/M (MBASIC release 5.2 orhigher; BASIC-80)
and Atari versions are user-friendly and come with
complete manuals. The Atari version requires 32K. The
CP/M version requires 48K. Both require at least one disk
drive. A printer is optional.

DYNABA8E DATABASE PROGRAM

(TRS-80, CP/M, and IBM only)

The DYNABASE DATABASE PROGRAM (DDP) is
an easy-to-use database package which may be
configured by the user. The program utilizes
sequential access techniques to eliminate the
requirements of setting limits on the size of any field,
and to make the most efficient use of available disk
space. The program functions have been structured
around the file access method to provide the least
amount of delay.

In operation, file size is limited only by available disk
space, and there are no artificial restrictions on the
length of text the user may enter into any field of a
record. DDP may be configured to contain up to 10
text fields plus up to 10 numeric fields. Each field is
labelled by the user.

A wide range of options is provided for printing out
the database during the print, sort, search, and
evaluation operations. Eleven "canned" printout
formats are provided, along with a custom printout
set-up option. The custom printout function allows
the user to set up a customized printout format
utilizing up to 255 columns. The set-up procedure
also supports control code sequences to select
printer density, font, etc. Once established a printout
configuration may be saved to disk for future use as a
printout configuration source. Printout routines
include page control, page numbering, dating,
source file name, and user heading.

The sort command allows the user to sort the data
file according to any text or numeric field. The sort
may be written to a target file, or may be used for
print out.

The search command provides a wide variety of
options for searching the data file. Results of the
search may be sent to a target file, or the search may
be printed out. The user can set up the "match"
conditions (3 text, 2 numeric), dr may select a range
search. Any number of fields may be selected for
searching, and up to 10 keywords may be entered
for matching. Both the text and numeric fields are
searchable.

A file evaluation command provides a math capability
for the numeric fields of a file. Addition, subtraction,
multiplication, and division are supported. (Begin¬
ning to sound like Visicalc"’?) The user may operate
on and store the results in any of the numeric fields
of the file. A constant may be substituted for one of
the operands, and an option to totalize all the
resultants of the file is also provided. The standard
add, subtract, multiply, and divide functions are
provided, along with the trigonometric, logarithmic
and exponential operators. DDP also permits
bar graphs to be printed, as well as mailing labels
(e.g., 1 -up).

DDP is user-friendly. All input data is requested by
name, and data verification is required before the
data is written to disk. The program is written to
reject out-of-range or nonsense inputs, and error¬
trapping is provided to prevent data loss due to
system errors. Easy to use editing features are also
provided. Price: $ 49.95 Diskette

lists, checkbook information, every kind of record.

FM PLUS comes with a 54-page manual which was
carefully designed to walk you through specific appli¬
cations and answer questions which may arise. The goal
is simplicity and ease of use!

REVIEW COMMENTS

From PC Magazine, July, 1984

"Many programs costing two to three times as much can
not do what (DYNAMASTER! can... you should be well
rewarded."

"Encourages high speed data entry...”

"One of the most powerful features of (DYNAMASTER! is
its ability to perform table lookups... This table lookup
feature is extremely sophisticated ..."

Since that review, DYNACOMP has acquired publishing
rights and, following our low price policy, has halved the
package price to $99.95.

STAMPS

(Apple, IBM, and TRS-80 only)

STAMPS lets you concentrate on the fun of philately by
saving time on the "bookkeeping" work of inventorying
and pricing your collection. It covers all U.S. stamps
indexed by the Scott Catalogue Numbers. Virtually
every issue listed in Scott's National Album is included.

All in all, STAMPS is a powerful, yet easy-to-use tool to
keep your collection current.

STAMPS also maintains a want list, complete with
prices; the computer never forgets what stamps you
want to purchase. When you add a new prize to your
album, STAMPS records the date and price of purchase
so you won't have to dig through receipts or trust your
memory later. When you sell a stamp, the program even
calculates your percentage profit.

There's also an electronic window into your collection
that lets you look up the value of any item, pinpoint its
location (at home or in your safe deposit box) — or take
a look at your entire collection without moving from
your computer.

As your investment grows, you can check its new value
each year with a special update disk that's available for
a minimal charge.

Features:

• Covers more than 2,500 U.S. postage stamp issues in
nine different grades.

• Uses convenient Scott numbers and instantly shows
current stamp values.

• Keeps you informed so you can sell right and buy

r «ght. .

• Tracks the value of your investment, automatically
updating prices each year.

Reports include:

• Value - Lists all stamps in collection, purchase price,
current price, and profit or loss.

• Summary - Calculates the bottom line purchase
prices, total value, total profit or loss.

• Stamps Sold - Gives details on cost and profit from
stamps sold.

Each STAMPS package includes the program and the
latest market value file for all U.S. postage stamps, all on
one diskette. There's also a clear and complete 32-page
instruction manual, owner registration form, and annual
update request form.

Requires two drives. An 80-column (or wider) printer is
required for printing out reports. The IBM version
requires 256K of RAM.

Price: $89.95 Diskette

Yearly updates to the catalog prices cost $25.00 (one
diskette).

Entering a coin is accomplished by referring to the Coin's
number from the standard coin list (included in the
system). Not only the coin's description (mint, date,
denomination, etc.), but its current value across most
grades is immediately displayed. You designate the
grade and the computer takes care of the rest. You may
include what you paid for the coin, and from whom it
was purchased. You may also alter the market value of
any entry. U.S. coins (other than the initial 1,600) and
proof sets and rolls may also be entered. A quantity
column allows tracking of duplicate coins.

Included in the COINS package are the disk, a 48-page
user's manual, and an annual update order form.
Updates cost $25 (plus shipping and handling).

Requirements: Apple (48K+), TRS-80 (48K+), or IBM
(128K+). Also, two drives and an 80-column (or wider)
printer.

MAIL LIST 4.0

(Apple only)

MAIL LIST 4.0 is an invaluable aid for the management
of extensive lists of names and addresses. Options
include alphabetical and ZIP Code sorting (over any
length ZIP Code), file merging, additions and deletions,
label printing (1-, 2-, or 3-up) and three different
printout formats. MAIL LIST 4.0 will even find and
delete duplicate entries!

One of MAIL LIST 4.0's most powerful features is a
virtually unlimited key-word selection capability. Any
number of three-letter user-defined key words may be
employed for each entry. Entries can be selected by key
word or unique combinations of key words, by name, or
by ZIP Code or ZIP Code range! Once selected, entries
can be written to the printer for producing address
labels or a special on-line format can be employed for
convenient record keeping. Selected entries can also be
added to other data files making MAIL LIST 4.0 one of
the most versatile programs of its kind regardless of
cost.

MAIL LIST 4.0 can handle 500 names per disk. An 80-
column (or wider) printer is required.

VIDEO CASSETTE DIRECTORY

(Osborne only)

VIDEO CASSETTE DIRECTORY (VCD) is a sequential
data file system, consisting of a main program and six
chained programs, which allows you to create, maintain,
and examine up to 500 records (18 fields each)
associated with a video cassette collection. If you are a
video cassette recorder owner whose collection of
recorded tapes has outgrown a manual inventory
system, or if you are a fledgling programmer who would
like to learn how to write data file programs in BASIC,
this sytem is designed for you.

VCD is menu driven, includes numerous on-screen
prompts, features CRT forms to facilitate data entry and
editing (with unambiguous prompts on 1 or 2 status
lines), checks input extensively for errors, and provides
12 formatted output options either to the monitor or
the printer. Eleven of the output options incorporate

MAIL MASTER II

(IBM only)

MAI L MASTER 11 is a comprehensive mail list manager for
name, address, and phone number storage and retrieval.
It also provides a 250-character comment section for
each entry and includes user-defined coded retrieval of
records (in addition to alphabetic and zip-code retrieval).
MAIL MASTER II does not require any disk or screen
display programming and is therefore immediately
usable. MAIL MASTER II is ideal for those desiring
computerized mail list records, and many of its functions
were designed with the idea of easily handling large lists.

Five lines are available for name and address, which
allows for the inclusion of titles and company references.
Since each can be individually edited, modifications are
easy. The comment section functions much like a word
processor; changes can be made without retyping the
entire comment.

On-screen messages inform you of the current file name,
its sort status, the date it was created or last sorted, and
the current number of records. Additional messages
remind you of the status of the displayed record. The use
of on-screen messages makes it easy to learn the program
and its capabilities.

The output can be either single-line or mailing-label
format. You can use any label width or number of
columns (1-, 2-, 3-, and 4-up). In addition, you may even
send control codes to your printer from within the
program to change the print characteristics, such as
condensed mode or the number of lines per inch. In
order to adjust paper alignment, the program will output
test prints. This saves on much of the "trial and error"
required by other mail-list programs.

MAIL MASTER II has been designed to offer you the
maximum amount of flexibility while maintaining speed.
You may merge files or split existing files, based on
alphabetical range, zip codes, or user-defined codes.
Individual files may be sorted into either alphabetical or
zip-code order. MAIL MASTER II will use either an in¬
memory sort, if sufficient RAM is available, or a disk sort
In both cases, no intermediate file is generated; files may
be sorted even when no additional disk space is avail¬
able. This maximizes how much you can save on a disk.
There is also a function to remove duplicate records from
a file.

MAIL MASTER II can store 1,200 names on a single 320K
disk. File size is limited only by available disk space (hard¬
disk compatible). In addition, the file structure is speci¬
fied so that you have the structure information required
to convert your data base files to MAI L MASTER 11 format.

Requirements: 128K, at least one disk drive, and a
printer. BASIC is not required.

Price: $99.95 Diskette

one or more sorts: alphabetical by title, numerical by
cassette number, or by one or all catagories of programs,
stars, directors, or studios.

Included with the program disk is an 87-page owner's
manual. A 12-page user's guide section discusses each
menu option, so there will be no surprises when you run
the program for the first time. A 22-page tutorial, and 47
pages of associated appendices, details the 'what, why,
and how* of each of the programs. It includes numerous
suggestions and instructions for modification of the
programs. In addition to the formatted easy-to-read
program listings, each of the programs is completely
outlined (e.g., flowcharts, variable cross references,
etc.), making the logic easy to follow. Careful study of
these materials will lead to an understanding of how the
system functions, how to modify it if you wish, and how
to apply those principles while writing your own data
file programs.

GOLFER’S DATABASE

(Atari only)

If you play golf or plan to, GOLFER'S DATABASE is for
you. Designed by an engineer with a two handicap,
this very easy-to-use program (comes with a 20 page
manual that's rarely needed) is designed to keep
track of your golf scores, number of putts, greens hit,
courses played, course ratings, course and weather
conditions plus other important scoring statistics.

As a data base you will be able to add, fcdit, delete,
search and sort your records as desired. A specialized
data file is generated by the data base which is used
to analyze various types of handicaps, stroke aver¬
ages and scoring characteristics.

All members of your family and/or golf leagtie can
have separate data files, each of which can be
reviewed and analyzed individually. If you have a
printer, all data records and analyzed output can be
printed. Included in the data base is a graphing
program which will plot and graph all your scoring

DYNAWORD DOCUMENT CREATOR

(IBM only)

Judged by what it does, DYNAWORD can be classified
as a "word processor". Judged by how it operates,
"digital typewriter" might be a better descriptor.

DYNAWORD is the practical, ergonomic, and economic
answer to the over-stuffed, hard-to-learn, hard-to-use,
over-priced mammoths which dominate the market
today.

In designing DYNAWORD, the undesireable features of
the current word processors were examined: the fatigue
associated with searching the screen for a flashing
cursor, the over-use of operator intervention to activate
every function, and the lack of correspondence be¬
tween the screen display and the printed document.

DYNAWORD has replaced the flashing cursor with a
highly visible "carriage" which always occupies the
same screen line; the document scrolls. Editing re¬
sponse is fast and consistent. Also, most format
operations can be pre-set and performed automatically:
right justification, dehyphenation for editing, pro¬
portional spacing, etc., all with a minimum of fuss. Also,
DYNAWORD displays the text on the screen as it will
appear on the printed document. As you type, the
justification takes place before your eyes!

An interesting extension of DYNAWORD is its ability to
manage and display word or screen page based
alphabetical files. These files can serve as a spelling,
checker, a thesaurus, or a general or specialized
dictionary. These files can also be created with
DYNAWORD. The process is fully described in the 94-
page DYNAWORD user's manual.

The active screen display shows the number of pages
saved in memory, a reminder of the available sub¬
commands in the current mode, as well as the text. Help
screens are also available.

Text file management is very efficient compared with
the currently popular word processors. With a 128K
machine, 54 manuscript pages can be stored in active
memory (RAM). With a 360K single-drive system, up to
230 manuscript pages can be saved (PCjr owners note:
you do not need to buy a second drive to use
DYNAWORD!). Any consecutive text page is displayed
in 0.22 seconds; any previous page in 0.68 seconds. This
is more than 30 times faster than two of the most
popular word processors on the market.

Text can be scrolled forward or reverse one line or
screen page at a time. Pages can be called up by
number. You can insert, replace, delete. Text can be
centered, justified, proportionally spaced, etc. Searches
can be made for strings up to 26 characters long,
including wildcard letters. Parts of files can be loaded,
inserted, saved. Even assembly language files (with 09H
codes) can be edited in the conventional assembler
source structure.

In short, DYNAWORD does a lot while being very easy
to use.

DYNAWORD requires 128K of RAM, one disk drive,
and MS DOS 1.1 or higher. It can be used with any 80-
column (or wider) printer. Compatable with the Tandy
1000/1200HD, AT&T, and Compaq.

CHINESE WRITER

(Commodore-C-64 only)

CHINESE WRITER is a Chinese language word pro¬
cessor system, it changes the Commodore 64 into a
Chinese typewriter which not only can type regular
sized, but also large-sized Chinese characters as well as
graphics. In addition, the text created can be saved to
disk and later manipulated.

The characters are saved on a database currently
occupying two floppy disks. Each disk contains space
for 6550 Chinese characters. At present there are over
1,300 characters in the database.

An editor is included to give you the ability to add,
change, or copy characters.

Dictionary utilities have been provided to print the
characters in the database along with their corre¬
sponding keys.

The system is very flexible. There is no limit to the
length of text files that can be created. The text itself
can be a mixture of regular and large Chinese characters
and graphics. Text files read from top to bottom, right to
left, are just as easy to create as files that read from left
to right, top to bottom.

The CHINESE WRITER system is designed to run on a
Commodore 64 with one Vic-1541 disk drive and a Vic-
1525 Graphic Printer.

addition, the "Macro" table, with English descriptions of
the different codes, can be displayed or printed out for
easy reference.

AWRITER offers complete flexibility in communicating
with peripheral devices. Input/output can be directed to
any device (printer, cassette, or as many disk drives as
your system uses).

With a 48K Atari and one disk drive, you start out with
approximately 22 K of memory available for text. For very
long documents, AWRITER will chain files together while
printing. You can also append files to text in memory to
piece together a document from standard files.

AWRITER makes it easy to prepare a very professional
looking document. Page numbering is handled auto¬
matically, as well as multi-line headers and trailers.
AWRITER even has sophisticated features like widow
handling so that a new paragraph will not start on the last
line of a page. You may select fully justified text, single or
continuous forms, starting page number, and so on.

If you need to use them, AWRITER has very powerful
features not included in many word processors. DOS
utilities are built right in so that you can get a disk
directory (with optional hard copy). You can also copy,
rename, erase, protect, or unprotect files, and format
blank diskettes. You may even edit BASIC programs.

If you do large mailings, AWRITER can save you much
time." Fill-in-the-blanks" forms can be used and can even
be interfaced to an AWRITER data base. AWRITER will
help you create a data base containing multi-field records
and you can command AWRITER to selectively retrieve
records from the data base. This feature is invaluable in
small business applications. The built-in data-base
manager can create data-base files, modify records, and
query records (with optional hard-copy listing).

AWRITER is one of the best, most powerful word
processors available for the Atari computer. It is easy to
learn and use for the beginner, and yet can meet the
needs of the most demanding user. And that's not all; it's
priced well below its competition, too.

scores for that week and NFL HANDICAPPER will give
you the handicap for the next week. That's all there is to it.
As for credibility, NFL HANDICAPPER has, in the past,

UNSOLICITED CHEERS!

Here is some enthusiastic (and unsolicited) correspon¬
dence from a user of DYNACOMP's HAN DICAPPER (and
he is not the first to contact us with such a glowing
report!):

"Using your HANDICAPPER program, I have hit 3 tri-
factas at Belmont Park, 2 at Finger Lakes, and 2 at Fort Erie.
I also hit the win-four at Fort Erie.

"Please notify me when you will have a handicapping
program for the harness-pacers and trotters."

S. Suska, Kenmore, NY

"P.S. The trifactas were won by boxing the three or four
top HANDICAPPER picks."

HARNESS HANDICAPPER

(Apple, IBM, and CP/M only)

HARNESS HANDICAPPER guides you step-by-step
through the analysis of each horse's past performance
chart in your track program by means of a series of easy to
follow screen prompts, questions, and menus. The out¬
put is a graded line of numerical ratings displayed on your
printer.

The program manual is much more than just an operator's
guide. Each step is clearly explained in relation to the
underlying handicapping principles. The insights pro¬
vided on the requirements for successful harness wager¬
ing are alone worth the price of the program.

The key to catching big payoffs in exacta and trifecta
wagering with limited investment is revealed in a unique
approach to the analysis of the graded line.

The author is a professional handicapper with more than
35 years' experience in both thoroughbred and harness
racing and is a member of the U.S. Harness Writers'
Association.

HARNESS HANDICAPPER requires 48K of RAM and a
printer.

HANDICAPPER

(available for all computers)

HANDICAPPER is a handicapping scheme designed
for thoroughbred races of lengths 6, 6 1/2, or 7
furlongs. It was designed by a mathematician and
has been tested by professional bettors and handi-
cappers. In general, you can expect HANDICAPPER
to produce the winning horse about 40% of the time.
However, in certain instances, it can be much more

The information required by the computer is:

1. The length of the race.

2. The length of the horse's previous race.

3. In some cases, the length of the next to last
race for the horse.

4. The horse's position at points of call in the
previous race.

5. The horse's position at points of call in the next
to last race.

6. The type of race today.

7. The type of the previous race.

8. The horse's post position today (determined
by his position in the RACING FORM).

9. The horse's post position in his previous race.

10. The number of first and second place finishes
for the past two years.

11. The number of starts the past two years.

As you can see, this is the same information used by
the professionals! The problem is, what if everyone
used HANDICAPPER?

HANDICAPPER II

(Available for all computers)

Now available after five years of research! HANDI¬
CAPPER II. The only complete handicapping system on
the market.

No system can work well unless it allows you to handicap
prior to the races, using past performance information,
and then look for the "overlays" at the track. Finding the
right bets at the track is very much like finding the right
stock to buy. Some are undervalued and some are
overpriced. To make money, you must pick the horses
whose odds for winning are greater than those set by the
bettors at the track. HANDICAPPER II does this using the
latest in scientific principles to calculate each horse's
probability of winning, given its past performance and its
position in the current race. Variables included are the
type of race, length of last race, previous positions at
points of call, lengths ahead or behind at finish of last
race, number of firsts and seconds in the last two years,
and the number of starts in the last two years.

As an extra bonus, you get the Kelly money management
system and a new technique for finding place and show
bets. HANDICAPPER II is the complete system for your
day at the races. For 6-, 6%-, or 7-furlong races.

The problem is, what if everyone used HANDICAPPER II?

STATISTICS

8L-MICR0

(IBM and CP/M only)

SL-MICRO is an easy-to-use statistical language which
should already be familiar to many users of statistical
packages on mainframes. SL-MICRO can process large
data files containing up to 32,600 cases with 200 vari¬
ables. Professional results are produced very rapidly.

The procedures implemented include frequencies,
crosstabs, condescriptive, Pearson correlation and mul¬
tiple regression, breakdown, and AN OVA (up to 5-way).
The frequencies procedure calculates counts and per¬
centages for categorical variables with statistics and
histograms as optional output. The crosstabs procedure
calculates two-way and three-way crosstabulation tables
and includes chi-square statistic. Both frequencies and
crosstabs can handle real and alphanumeric data as well
as the usual integer data. Condescriptive calculates de¬
scriptive statistics. The Pearson correlation procedure
also includes the t-statistic and a covariance table as
options. The multiple regression routine performs either
stepwise or blockwise multiple linear regressions. It can
also do polynomial regression by using the data transfor¬
mation routines to calculate quadratic or cubic terms.
Interaction terms can be calculated in the same way. The
user can also specify the order of inclusion of variables in
the equation using hierarchial inclusion levels. The
Longley regression test has been used to check accuracy.
SL-MICRO produces coefficients to the same accuracyas
SPSS on a mainframe.

SL-MICRO includes a powerful group of data transforma¬
tion and selection commands. The compute command
can calculate new variables from existing variables using
simple algebraic expressions. The recode command can
be used to categorize metric variables or to convert
alphanumeric to numeric variables. The IF command
allows the user to calculate new variables only under
specified conditions. The SELECT IF command selects a
subset of the data file for processing. SL-MICRO also has
functions including logarithmic and trigonometric which
can be used for more complex operations.

SL-MICRO includes many features to make your output
more professional and easily understood. Thes6 features
include variable and value labels, report titles, and long
variable names. The output is designed for eighty-column
printers.

Other features have been provided to make SL-MICRO
easy to use. These features include English error mes¬
sages and missing values processing in all statistical
procedures. SL-MICRO is also compatible with most
database systems. It can read files with either fixed-field
records terminated by carriage returns or with comma
delimited fields. You can also use most word processors
or text editors with SL-MICRO.

Analysis of Variance

SL-MICRO isavailable for the IBM PC under PC-DOSand
for most machines running MS-DOS. It is also available
for CP/M-86 in IBM PC or 8-inch formats. Both 16-bit
versions require 128K of memory and two disk drives or a
hard disk.

CP/M versions are available for Kaypro, Osborne, Apple,
etc.

STATISTICS

SPRINQ-STAT'
MULTIVARIATE STATISTICS

(IBM only)

SPRING-STAT is designed to meet the data analysis
needs of business, social science, market research,
economics, financial, engineering, and academic
professionals. While these needs have been met in the
past by mainframe packages (and more recently by
downscaled or expensive versions of these packages),
SPRING-STAT offers some unique features:

• It's comfortable to leam and use. The entire system
is prompt/menu driven and interactive.

• The system is integrated and modular. This means
that you need buy only those modules that you want
It's a low-risk way to familiarize yourself with the.
system. If you like what you've bought, you can atway<
add more modules.

• The 200+ page manual covers all aspects of the
system. Sample data and on-screen instructions are also
included.

• Data is stored in ASCII format which means that it's
relatively easy to exchange data with other sources. The
SCREEN EDITOR MODULE can aslo read DIF files.

The following provisions are available in modules (see
below) for entering and editing data:

The DATABASE MODULE allows up to 10,000 records
with up to 500 variables (fields) per record. You can
design custom databases interactively and add records,
delete records, change fields within records, search and
sort records, and design custom report formats. You can
also append files and create sub-files that include
only those variables that you specify, and only those
records that meet the conditions you indicate. In fact,
you can use this database module for non-statistical
applications (mailing lists, record catalogs, etc.) because
all the data is stored in ASCII format.

The TRANSFORMATION MODULE allows you to create
one or more new variables using a BASIC-like inter¬
preter that supports arithmetic ( A , +, —, *, /), logical (IF,
THEN, ELSE, AND, OR, >, <, >=, <=, «, <», and
function (SQR, SIN, COS, TAN, ATN, INT, LOG, EXP,
ABS, NEG) commands. You can include up to 26
existing variables as well as numeric constants when
creating the formula for computing a new variable. The
TRANSFORMATION MODULE also allows you to
recode variables (alphanumeric codes can be changed
to numeric codes; continuous variables can be changed
to categorical values representing intervals), and to
transform variables to normal or standardized scores.

A spreadsheet-like SCREEN EDITOR MODULE is
available for handling smaller jobs. This editor can read
and write files that are compatible with the DATABASE
MODULE, read/write files in its own unique format, and
read DIF files. If a job is relatively small (a maximum of
40 observations and 20 variables), this module can be
used to create and edit the data in a more convenient
fashion than when using the DATABASE MODULE. This
module is the only data entry/edit method acceptable
to the MULTIDIMENSIONAL SCALING AND HIER¬
ARCHICAL CLUSTERING MODULE.

STEPWISE

MULTILINEAR REGRESSION

(Available for all computers except Atari)

STEPWISE MULTILINEAR REGRESSION (SMLR) is an
add-on module to be used with MULTILINEAR REGRES¬
SION (MLR); you must have MLR to use this module.

SMLR performs an analysis somewhat differently from
MLR. It fits variables in the order of their importance,
thereby giving an indication of what the contribution is of
each. If a variable does not significantly reduce the
variance between the data and fit, it is dropped. This
permits you to determine the main variables influencing
your data.

SMLR also has the advantage that it can handle larger
data sets than MLR. Other features provided by SLMR
are:

• Variable naming (optional)

• Variable switching (even dependent—independent)

• Variable addition to a data file

• Variable removal from a data file

• Listing of data versus fit, including differences and
percent differences

• Predictions for other data points

• Student-t confidence limits on predictions (Student-t
values calculated internally—you do not need to use
tables)

• R, R 2 , and standard deviation of fit

• Correlation matrix

• Printer/screen option

• Display of fit statistics as each variable is added

The number of variables and data sets is limited only by
memory size. For example, most 64 K machines can easily
handle cases involving 10 variables and 200 data sets.

What SMLR does not do (which MLR does do) is give you
estimates of the coefficient standard errors (which is very
useful). However, calculating the errors in the coeffi¬
cients consumes a great deal of memory and is slow to do.

Requires at least 32K and one disk drive.

STATSORT also interfaces well with other programs.
STATSORT can share files with word processing programs
as well as the Radio Shack statistics package. By itself,
STATSORT can create, edit, sort, and merge files and
perform statistical analyses on numeric fields. All-in-all a

REGRESSION I

(available for all computers)

REGRESSION I is a complete and coordinated regression
curve fitting package for the analysis of linear and non¬
linear, one-dimensional data It is based on various sub¬
routines and techniques presented in Volumes 1 and 2 of
BASIC Scientific Subroutines (by F. Ruckdeschel).
REGRESSION I provides many of the facilities available on
large FORTRAN-speaking machines and more However,
unlike many of the FORTRAN equivalents, there is no
confusion as to the input/output variable formats, and the
software is very easy to use In addition, the analysis is
interactive^ thereby permitting the user considerable freedom
in experimenting with fitting functions and orders of
approximation. Also, a special algorithm is employed to
- determine the coefficients which has round-off error
properties much superior to the matrix algorithms
commonly used. This greatly reduces the need to perform
the calculations in double precision or pre-process the
data

The features of REGRESSION I include:

1. Easy data entry and editing

2. Automatic data sorting and plotting (of both the data
and fitted curves).

3. Fast and accurate regression.

4. A choice of many fitting functions, including forms
supplied by the user.

5. Analysis of the standard error of the derived coefficients

% and the correlation coefficient

J 6. Data storage and retrieval.

Once the regression has been performed, the user may
I immediately repeat the analysis using the same data set

I (with editing if desired) and test other functional forms.

REGRESSION I is not only a powerful statistical tool for use
in the engineering business and social sciences, it is
educational as well. Because the program presents the
regressed coefficients as well as their estimated error
bounds, the student may learn by experience how much
credence to place on the derived coefficients. In addition,
he/she may also get a feel for the general types of fit
associated with various levels of correlation. It is very easy
for the inexperienced experimenter to be tricked by
regression results, especially those having high R 2 values.
REGRESSION I is designed to guard against this.

Accompanying REGRESSION I is a well-written 12 page
users manual

Requires 16K of program memory (Atari version requires
24K).

REGRESSION II (PARAFIT)

(available for all computers)

PARAFIT is a parametric least squares regression program
designed specifically for the determination of the non¬
linear coefficients in complicated mathematical expressions.
This is to be contrasted with the linear polynomial coefficients
calculated by REGRESSION I.

A typical problem suited for analysis by PARAFIT might be
the following Information has been collected on the
failure rate of a particular product This information is in the
form of the normalized fraction of items which failed per
unit time interval after production. The times at which
these data were collected may not be equally spaced such
that the set consists of many (fi, ti) pairs. The functional
form assumed is the Weibull distribution.

f(t)=[^^ ) j exp [ (t/u) v j

Given the fi, ti) data pairs, what are the least squares
regression values for the parameters u and v?

PARAFIT may be used to solve this problem. The user
inserts the functional form as a BASIC program statement
and runs PARAFIT. The program employs a special form of
modified steepest descent to interactively determine the

MULTILINEAR RE8RES8I0N

(available for all computers)

This is the third program in the DYNACOMP statistics
series. Whereas REGRESSION I and REGRESSION II
(PARAFIT) are designed for analyzing bivariate data,
MLR is capable of treating multi-variate situations with
no limit (other than available computer memory) on the
number of dimensions. The general form of the equation
fitted will be Y= afi(Xi) + bfc(X 2 ) + cf3(X3) + etc The
variables are the Xi .The regressed coefficients are a, b, c,
etc. The functional forms, fi(Xi), may be virtually any¬
thing MLR automatically offers a choice of nine mathe¬
matical forms, including the logarithm and exponential,
as well as the simple default fi(Xi)=Xi. In addition, the
user may replace the default form with his own function.
These choices can be independently made for each
dimension.

The data input to MLR may be either from the keyboard or
from cassette/disk files. Data may be loaded, saved, added
to, deleted, and generally edited using the convenient data
manipulation procedures provided. The number of data
points is limited only by the computer memory available.

The outputs from MLR are the regression coefficients and
the standard error associated with these coefficients. Such
error estimates are very useful, but often neglected by
regression programs. MLR also supplies the standard error
of the estimate for the fit and the correlation coefficient
Finally, MLR offers the opportunity to use the regressed
equation to calculate values along the fitted hyper-curve.

8TATTE8T

(available for all computers)

STATTEST performs statistical tests of hypotheses and
includes t-tests, chi-square tests, and F-tests as well as
simple regression and a random number generator.

Data can be entered under program control or from tape or
disk. Any external file which already contains data in the
simple format required may also be used. Once the data is
loaded, it may be edited by the program's own data
manipulation routine. Data can be changed, added,
deleted, or any combination thereof. Data can also be
listed upon entry and after editing if desired.

When the data is ready, descriptive statistics are calculated,
the hypothesis to be tested is stated, and the test is
performed. Previously calculated statistics may be
optionally used instead of data entry.

Operationally, MLR employs two distinctly different methods
for finding the regression coefficients. The first method
uses matrix algebra techniques and is quite fast The
second method utilizes a very stable form of steepest
descent optimization. This second approach is much
slower in execution, but requires significantly less computer
memory and can handle “ill-conditioned" situations with
high accuracy. Also, with this technique, the fit is made one
dimension at a time, and the coefficients and standard
error of the fit are displayed at each step.

MLR is supplied with a 16 page manual which carefully
outlines program operation.

Requires at least 16K of program memory (Atari version
requires at least 24 K).

REGRESSION III
(The Calibrator)

(Available for all computers except Atari and C-64)

REGRESSION ill is a special applications-oriented curve¬
fitting package designed to be used for generating cali¬
bration curves or other fits based on the mini-max
principle.

Virtually all polynomial regression procedures (e.g.,
REGRESSION I) use the criterion of minimizing the
standard deviation between the data and the fitted
polynomial. This goal has considerable merit, statistically.
However, there are many situations in which this is not
the correct criterion. For example, if you have a compu¬
terized thermocouple temperature measurement instru¬
ment, and you want a polynomial with which to convert
the thermocouple voltages to temperature, the desired
curve fit should minimize the maximum difference be¬
tween the true and displayed temperatures. Minimizing
the standard deviation does not do this; mini-max does.

In the application which prompted development of this
program, the specified accuracy of the measurement
device was improved by over 60% without any change in
the instrument; mini-max coefficients were used instead
of standard regression values! When doing high order
(e.g., N> 8 ) order fits, a ten-fold or better reduction in
maximum deviation is often achieved by using mini-max
rather than straight least squares.

• Easy data entry and editing.

• Full data file compatability with REGRESSION I and
REGRESSION II.

• A choice of many data transformations; the user may
even program in his own.

• Data storage and retrieval.

The outputs from R EGR ESSIO N111 are the polynomial co¬
efficients and the minimized maximum error.

REGRESSION III may also be used to generate mini-max
polynomial approximations to functions for use in appli¬
cations such as replacing tables or providing higher speed
calculations. Such approximations are routinely em¬
ployed in interpreters and compilers (e.g., BASIC,
FORTRAN), or programs which repeatedly calculate
complicated functions.

Requirements: The order of the polynomial fitted and
the size of the data set is limited only by available
memory. You should be able to handle most cases of
interest with 48K of RAM. Written in BASIC.

NON-LINEAR

PARAMETER REGRESSIION
-PARAFIT II -

(CP/M and IBM only)

Have you ever needed a powerful and versatile non¬
linear regression program which would fit complicated
equations to experimental data to determine the un¬
known parameters? If so, read on.

PARAFIT II is generalized so that it will fit to any function
that you may wish to define within the syntax constraints
of the program. For example, given a set of data points (up
to 200 for 128K, 50 for 64K) you may determine the A, B,
C, etc., parameters (up to 10 for 128K, 5 for 64K) in
equations like:

f(x)=A*exp(B*X"2) (statistics)

f(x)=A*X‘(B*X) (chemistry)

f(x)=A*sin(b*X)/X (engineering)

f(x)=A*sin(B*X—C)+D*sin(E*X—F) (seasonal forecasting)

f(x)=A/X*cos[B*(X-C)l+D*expl—E*(X—F) 2j (???)

Such equations are often encountered in science, eco¬
nomics, and industry. For example, the first equation is
the Gaussian, which is often encountered in statistical
problems (it could just as well have been the Weibull
function, etc.). The second equation is the exponential,
which could be encountered in reaction kinetics or sales
forecasting. The third equation is a damped sine wave
(possibly encountered in electronics or control systems).
The fourth equation is a two frequency sinusoidal which
might be used to unravel cyclical stock market action,
seasonal sales, etc.). The fourth equation is weird.

PXRAFIT II goes out of its way to let you input data in
whatever manner you prefer. All data may be entered
from the keyboard, or part of it can be entered from disk
simply by telling PARAFIT II what disk file to read to find
the necessary information. Or some disk file input may be
used interspersed with keyboard input

The equations are entered by simply typing them in when
prompted. The functions available for constructing these
equations are: +, -, *,/, *, =, SIN, COS,TAN, LOG10, LN,
EXP, ATAN, ABS, and SQRT.

You may use BASIC-like structures or reverse Polish.

Up to ten unknown parameters may be determined. Each
parameter may be initially specified, and there is com¬
plete freedom in holding some parameters constant
while varying others, etc.

In calculating you may specify the maximum number of
iterations allowed as well as when to quit according to
how much the standard deviation of the fit has changed.
At each step you may display (or print) the current
standard deviation and parameter values. The final re¬
sults are the fitted parameters, their standard errors
(including % confidence) and the standard deviation of
the fit. Also available are:

• a plot (or list) of the data and the fit.

• The partial derivative matrix.

• The parameter correlation matrix (test for inde¬
pendence).

Other features include optional data weighting, optional
derivative specification, and a choice of two iteration
schemes, fast Least Squares Matrix Analysis, and a slower
(but very stable) algorithm for use on "tough" problems.

PARAFIT II is written in machine language for speed;
MBAS 1C is not required.

Requires 64K (CP/M), 128K (IBM).

A printer is supported, but optional.

MULTIPLE REGRESSION AND
MULTIPLE/PARTIAL CORRELATION

(Apple only)

MULTIPLE REGRESSION AND MULTIPLE/PARTIAL
CORRELATION was designed with the statistician
in mind, and is reminiscent of the statistical routines
provided on the large mainframes. First you may
build and edit files with the options of changing
data, adding data, increasing/decreasing the number
of variables, increasing/decreasing the number of
individuals and shuffling variables or individuals.
These data may be saved or recalled from disk (the
same file format as used in PRINCIPAL COMPONENTS
AND FACTOR ANALYSIS). Then you have the choice
of running stepped regression or multiple regression
with partial correlation. The stepped regression

examines the variables one at a time, choosing in
turn the one which explains the most residual
variation. For stepwise regression you are provided
with the regression equation, standard errors of the
coefficients, regression analysis of variance, and the
correlation matrix. For multiple regression (without
steps) you may also perform partial correlation with
respect to any given variable, and the regression will
be done with and without that variable.

All the functions are menu driven and the user
prompts are simple and straight forward. The disk
data file format is simple, making is easy to convert
your current data files into a format acceptable to
MULTIPLE REGRESSION AND MULTIPLE/PARTIAL
CORRELATION.

MULTIVARIATE REGRESSION
ANALYSIS

(TRS-80 and IBM only)

MULTIVARIATE REGRESSION ANALYSIS (MRA) is a
DYNACOMP statistics package which compliments
MULTILINEAR REGRESSION (MLR). In essence, MRA
approaches multivariate regression from a different
computational perspective. This approach is a little
slower and does not include standard errors of the
estimates for the calculated coefficients. However, it
does handle much larger data sets, and has a few
different features. Besides the standard data editing,
variable removal, etc., capabilities, MRA also includes
the following:

• Reverse stepwise regression.

• Up to 54 named variables (9,999 observations for six
variables).

• Tables of means, standard deviations, correlation
coefficients, partial correlation coefficients.

• Min, max, skewness, and kurtosis for each variable.

• Correlation eliminations (by calculating coefficients
for cross terms, squares, cubes. For example, the E
and F in (X-E). * (Y-F).

• User defined (in BASIC) variable transformations.

• Regression coefficients, beta coefficients, F ratios,
R-squared.

• Binary-to-decimal correction (to avoid single/double
precision data file loading problems).

• Double-precision square-root routine.

• Calculation by correlation matrix inversion to reduce
error.

• Matrix inversion test for poorly conditioned data.
Inverse diagonal display.

• Residual analysis with Durbin-Watson D, one-sided
U statistics.

• Scatterplot of residuals vs. dependent variable.

• Plot of residual distribution compared with normal
distribution; chi-square statistic.

• Probability plot of residuals (should be straight line).

MRA comes with a 43-page manual which includ
sample run information. A printer (at least 64-colum
wide) is supported, but not necessary. Requires 4
(TRS-80) or 128K (IBM) to run all modules. The me
memory, the larger the data array you can run.

ARGUS PERCEPTUAL MAPPER

(IBM only)

ARCUS is a multidimensional scaling (MDS) and Hier-
archial Clustering package for discovering hidden struc¬
ture in data tables. Data can be entered either as dis¬
tances (dissimilarities) between pairs of objects, or as
profiles of objects on a set of attributes.

ARGUS transforms this data into a two-dimensional
graph that shows the objects as labeled points and the
attributes as labeled vectors. A tree diagram showing how
the objects cluster together on the basis of profile simi¬
larity, is also displayed.

While MDS and Clustering are "leading edge" statistical
tools, they have the unusual property of lending them¬
selves to easy visual analysis and interpretation. ARGUS
can thus be immediately useful to both laymen and
professionals. It's a pattern-recognition aid that can pro¬
vide an analytical edge for examining data sources rang¬
ing from survey tables to marketing summaries to spread¬
sheet matrices (ARGUS can read DIF files)

Working with ARGUS is straightforward and comfortable.
It's menu driven, with a highlighted block pointer for
each option to minimize typing errors when making
choices. Data are entered and edited using a spread¬
sheet-like screen which also supports a full range of
arithmetic and logical calculations for creating new var¬
iables from existing ones. Most file handling functions
can be done from within the program without exiting to

initial estimate, MDS is then performed with the follow¬
ing intermediate output: Normalized Euclidean distance
matrix, step-by-step iteration history, plotting coordi¬
nates of objects and attributes, map of objects and
attributes, tree diagram of clustering process.

While most of this information is implicitly contained in
the maps themselves, the detailed tables for building the

alter your raw data by increasing or decreasing the
number of variables or "individuals", as well as
shuffle both the variables and individuals. All in all,
PCFA is a powerful multivariate analysis package.
{Note: Although PC FA does the calculations, it is left
to the user to evaluate the results. Therefore some
familiarity with the subject is required: references
are given).

Price: $49.95 Diskette

The CP/M version requires Microsoft BASIC, release 5.0
(BASIC-80) or newer, and 64K of RAM. The Apple
version requires 48K of RAM. A printer is supported but

DATA SMOOTHER

(available for all computers except Atari)

This package provides the user with a fast and easy means
to least-squares smooth equally spaced data and plot the
results. Any size data set may be treated within the
memory limits of your machine The variation in each data
point is smoothed according to the weighted average of
points surrounding it The averaging span is 3 to 2 5 points.
The order of the local smoothing is linear to qumtic (first to
fifth degree polynomial). Also calculated are the smoothed
first and second derivatives of the data at each point

The width of the plot is user-controlled. The software
automatically considers the printer width chosen and
number of data points to produce a graph having a good
aspect ratio

This program is very useful for smoothing out day-to-day
stock market fluctuations in order to determine underlying
trends. It is also beneficial to the business man in planning
inventory based on varying sales volume The scientist and
engineer may apply the smoothing software to noisy data
sets. Communications engineers can apply it to incoming
data as a "digital filter."

DATA SMOOTHER is extremely well documented in the
accompanying 38 page manual which describes both the
theory behind the program, as well as its use

Requires 16K. Price $19.95 Cassette

STATISTICAL SAMPLE PLANNER

(Apple, CP/M, IBM, and TRS-80 only)

STATISTICAL SAMPLE PLANNER makes it easy to find the
sample size and strategy that best meet your needs. This
friendly program is for you if you're concerned with
questions such as these:

Should I stratify or would simple random sampling
be better?

If stratification, should I sample by a proportional
approach or would I save riioney and still achieve
necessary statistical precision with an optimum allo¬
cation strategy?

How should I proceed to achieve given standards of
precision at the level of individual strata as well as at
a population level?

For pre-specified precision total sample size, what
precision and cost can be expected?

For pre-specified precision standards what sample
sizes and costs will be required?

What is the smallest sample that will meet my needs?

How can I capitalize on information about individual
strata (size, distribution shape, range, variation,
sampling expense) to efficiently accomplish my
sampling goals?

STATISTICAL SAMPLE PLANNER will be of value to you if
you apply sampling techniques to survey research,
market analyses, quality control or other areas involving
random sampling of independent units. STATISTICAL
SAMPLE PLANNER will quickly compare the benefits of
optional plans you want to consider. It also makes an
effective tool for teaching sampling. A clearly written 28-
page manual includes theory, formulae, examples, pro¬
gram listing and references.

Requires 48K.

ANALYSIS OF VARIANCE

ANOVA

(Available for all computers)

(Not available on Atari cassettes)

ANOVA is actually four programs in one Each program
performs a specific task matched to the designed experi¬
ment under analysis.

1. A one-way ANOVA produces the treatment sum of
square, mean square, and F ratio along with the error
mean square. This algorithm accepts unequal numbers
of replicates per treatment level and unlimited numbers
of treatment levels and replicates.

2. Two-way ANOVA performs an analysis of either fixed
or random factors with equal numbers of replicates
(repeat measurements) per cell. There is no practical
limit on the number of levels or replicates. Sums of
squares and mean squares are printed for both factors
and the interaction as well as the error sum of squares
and all F ratios.

3. The" N-way" (for N up to 5 factors) will accept up to4
levels per factor or any combination of levels not to
exceed 1024 treatment combinations in 16K of core.
Sums of squares and mean squares for all main effects
and up to 3 factor interactions are computed. The
appropriate (residual or pure error) mean square is
used to compute the F ratios.

4. YATES analysis computes the mean square and half
effect for two level factorial and fractional factorial
experiments. All main effects and interactions are
computed and printed out.

In all programs except the YATES, the means for the main
factors are printed. Unlike many large computers
FORTRAN-based ANOVA systems, data entry is interactive
and at the user's option. A data file may be created for
editing and re-entry at a later time.

Documentation (15 pages) includes a guide to experimental
design and methods to compute components of variance
for the random model ANOVA Examples and test data are
provided to allow the user to practice with known informa¬
tion before applying the programs to their own data

Requires 16K program memory space.

I CHINO

CANON OF CHANGE

(Apple and IBM only)

Three-thousand years ago, revolution brought down the
house of Shang in China, and the mandate of Heaven
passed to Zhou. Thus ended the era of the tortoise
oracle and bronze vessels and began the great dynasty
that saw the rise of Chinese philosophy. The Zhou
people knew the deepest secret of the universe, that
Yin and Yang are at the root of things, that they
continually change into each other, giving motion to the
world. They expressed this in their oracle / Ching, the
Cannon of Change.

Woven into the / Ching are the beliefs, values, and
poetry of the Zhou people at the beginning of their
millenium. The book has always been more than mere
oracle to the Zhou people, who created it, and to
generations that came after.

Confucius, born five-hundred years after the / Ching,
saw it as the guide to proper conduct in harmony with
Nature. His teachings remain deeply ingrained in the
culture, not only of China, but also of Japan, Korea, and
other countries of East Asia.

There is also a Western tradition of the / Ching which
brings fresh insights from new points of view. Gottfried
Wilhelm Leibnitz (1646-1716), the German math¬
ematician who invented calculus, credited the / Ching
with the notion of binary integers, the stuff of modern
computers. Carl Gustav Jung (1875-1961), Swiss psy¬
chiatrist, has championed the use of the / Ching as an
analytical tool in psychology. Between these weighty
applications, the I Ching has been used as fortune teller,
aid to meditation, and forecaster of the stock market.

The new translation of the / Ching used in this DYNA-
COMP program aims to restore the original face of the
book as it was written three-thousand years ago. To that
end, the findings of modern archeology and scholarship
have been used to help decipher the meaning of words
and phrases in the Chinese original. Such a rendition
will serve the modern user who considers value
judgement an individualistic and personal thing.

Indeed, the universal appeal of the / Ching lies in that
combination of charm and depth that, while main¬
taining its own integrity, allows all comers to use it in a
personalized way.

According to the author, Dr. K. Huang, a professor of
physics at M.I.T., computerizing the / Ching is a natural
extension of the written version. Reason: choosing a
passage in the book used to require flipping three coins
six times each to choose one of the more than 4,000
passages. Since computers are expert at generating
random numbers, the machine does the "flipping" and
picks the correct passage.

The interest in / Ching has increased in recent years
because of the closer ties with the East. This / Ching
program has even been discussed in V.S. A Today (July
19, 1984) and The Wall Street Journal (June 4, 1984).

eligible for further quantity (10%-20%) discounts.

TIME SERIES / FORECASTING

(Apple only)

TIME SERIES is a menu-driven package consisting of
several programs for data file creation, editing, and
analysis. The analysis routines are largely based on the
methods discussed in the text by Freund and Williams.
The TIME SERIES files may be examined using one of
three trend models: linear, quadratic, and exponential.
Detrended and detrended/deseasonalized data files can
be set up while running the time series analysis, and they
may then be tested using the autocorrelation routine
(included). This allows you to determine how well the
model works by examining the residual for randomness.

The manual and disk include a time series data example
derived from the text

Requires 48K. Price: $29.95

REGRESSION ANALYSIS: Use up to seven explanatory
variables and six-hundred observations. The coefficient
of determination, its corrected version, the standard error
of the estimate, the F value, and the standard errors of the
parameter estimates are included in the main output.
You may select correlation coefficients of the indepen¬
dent vairables or a forecast module that allows for predic¬
tions and storage in a data file.

GENERAL STATISTICS: Sort and rank according to ordinal
or cardinal values. Other features include frequency
distributions, summary statistics (mean, median, mode,
skewness, variance, standard deviation, and coefficient
of variation). You can perform an autocorrelation test to
check for stationary. Simple correlation and elasticity
estimates are easily developed. Forecasts can be tracked
against actuals, with several statistics.

DIF FILES: Provides translation of data so that you can
interface to popular programs such as Visicalc™ and
Lotus™.

RESIDUAL ANALYSIS: Allows the listing of residuals, their
autocorrelation function, the fitted values, and the
Durbin-Watson statistic.

Both the software and manual are designed for ease of
use and convenience.

Requires 128K (IBM PC), 48K (Apple), and one or two
disk drives. A printer is supported, but not necessary.

FOURIER ANALYSIS FORECASTER

(CP/M and IBM only)
INTRODUCTION

FOURIER ANALYSIS FORECASTER (FAF) has been
under development by DYNACOMP for quite some
time. For years, people interested in stock market
forecasting, as well as analyzing other cyclic phenom¬
ena, have been using DYNACOMP's popular FOURIER
ANALYZER and HARMONIC ANALYZER. From our
many discussions with individuals involved in such
efforts, our staff has formed a fairly clear understanding
of what software tools are really required to perform the
needed calculations.

Theoretically, ARIMA forecasting in its full imple¬
mentation is capable of handling predictions involving
cyclic data. However, FOURIER ANALYSIS is really more
appropriate, and the ability to explicitly determine the
periods of the underlying cycles is much more useful
both conceptually and in relating the calculations to the
real world.

Although FAF is targeted specifically at stock market
analysis, the procedures used are equally well suited to
cyclic data in general. It is not assumed that you
understand Fourier analysis. Instead, the manual takes a
very tutorial approach to presenting the ideas involved
in the Fourier series and how data can be looked at in
terms of sine waves. Extensive use is made of graphical
examples so that you can visualize what is going on.

The software also does not assume familiarity with
even much mathematics! For those interested in the
coefficients which go with all the terms, the standard
errors, etc., they are all provided, including displays of
the fitted equations. However, you can also rely on
looking at plots, or simply use the data-versus-
prediction tables. Without understanding any of the
mathematics you can employ FAF to automatically do a
very sophisticated analysis, predict future values, and
give you an estimate of the certainty (the range) of the
prediction!

In short, through years of product research, DYNA¬
COMP has determined both the need as well as
evaluated the skill level of the potential user. It then
took more than a year to prepare the product.

HOW IT WORKS

First you enter your data from keyboard or from a disk
file, save it, add to it, edit it, delete it, etc. That sounds
trivial, but it sure helps to have a convenient way to
enter, save, and recall your data.

The basic assumption is that the data to be analyzed can
be broken down into two general components: an
underlying trend, and a multi-cyclic pattern. The types
of trends which can be fitted are:

Polynomial (linear, quadratic, or cubic) in time (T) or

inverse time (1 /T) trends

Exponentially increasing/decreasing trends (single,

double exponential)

Logarithmic trends

These trend capabilities go far beyond what we have
seen in other products and can even handle some fairly
weird situations (electrical engineers can even fit
Laplace transforms to spectral data!). Also, you can
choose to either subtract the trend from the data, or
divide by it (recommended for stocks/commodities).
Once you have chosen the type of trend to be fitted (or
none at all), FAF will automatically proceed to calculate
the required coefficients and remove the trend from the
data, report the form of the trend formula, and give the
standard deviation of the fit as well as the confidence
limits for the coefficients found. Then FAF automatically
analyzes the de-trended data for its frequency com¬
ponents.

The Fourier analysis phase is completely automatic. FAF, : *
in sequence, finds the dbminant cyclic (sine wave) ;>
component, removes it from the data, and goes on to
the next component (a form of STEPWISE NONLINEAR *
REGRESSION). Each time it calculates the standard
deviation. When the sample standard deviation ob¬
tained at each step no longer decreases, the fitting
("decomposition") stops.

You are then presented with all of the information on ;
the fit You can plot or display the data, the fit, or both
simultaneously. You can look at (plot or display) the
"residuals" (differences between original data and fit;
the "error" curve), and analyze the residuals if you want
to. You can also project out into the future and (using
the very special Monte Carlo analysis feature) even
estimate the confidence of your projection! You can
look at the trend curve by itself, save your plots in disk
files, etc.

As you can see from this narrative, you can go through
the analysis studying all the coefficients, or simply have
the computer calculate to its conclusion without
observing the inbetween steps. In the end, you can look
at the fitted formula, tables, or plots. This covers quite a
range of user experience and interest.

FORECASTING/SALES

BALLISTICS

MARKET MODEL

(IBM only)

MARKET MODEL is a market simulation model for
organizing information about a brand/product and its
competition, and then estimating the probable effects
of various marketing strategies on market share and
volume. It can save you hundreds of times its price (or
more!).

Marketing people are always facing questions of how
price, advertising, quality, distribution, new launches,
product mix, competitor action, etc., affect market share
and volume. Definitive answers to these kinds of "what-
if" questions are not available, and the best “real world"
estimates are only possible through carefully controlled
experimentation in test markets. Such experimentation
can be both costly and time consuming. And there are
still severe limits on how many factors in the marketing
mix that can be examined simultaneously. However, a
rough examination of various scenarios can be made
through computer simulation.

While financial planning models and spreadsheet
overlays for microcomputers are plentiful, these models
do not provide estimates (forecasts) of demand ... they
merely estimate the financial consequences of different
demand levels.

MARKET MODEL fills this gap by providing a model
based on competitive market dynamics which relates
marketing mix decisions to demand as expressed by
share and volume. Data from syndicated services
(SAMI, NFI, LNA), internal data sources, and expert
judgement are used as initial input for fitting the model
to a particular market. Once the existing market has
been replicated to satisfactory tolerances, MARKET
MODEL can then be used to run “what-if" simulation
experiments.

Although the model provides the flexibility for custom¬
ization (it's not just a set of fixed-parameter equations),
it's easy to work with and does not require the degree of
sophistication that's necessary to build an econometric
model from scratch.

Over ten years of "hands-on" consulting experience
with new and existing products in all kinds of categories
are incorporated in the model, so, in a sense, MARKET
MODEL is a marketing strategy “expert system". As a
result, you don't have to worry about what kinds of
variables to include or how to put these variables
together to capture the dynamics of your market. While
these matters are taken care of by MARKET MODEL,
you still need to expend some effort in planning your
project, gathering your data, fitting the model to this
data, and interpreting the results. However, you don't
have to be an econometrician in order to do this.

The net benefit is that you spend relatively little time to
build a custom model, and can thus concentrate most of
your time on running simulations and getting feedback
on alternate strategic policies. The advantages of being
able to “bench test" strategies prior to major commit¬
ments of time and money are obvious.

Fitting the model, and running simulations can also
provide interesting insights about implicit assumptions
regarding “what makes the market tick”, and how these
assumptions hold up when the available information is
examined objectively.

Among the many features are:

• Variables included for each product:

Advertising expenditure
Advertising effectiveness index
Product quality index
Price per equivalent unit
Distribution/point-of-purchase index
Unit share in previous time period
Unit share in current time period
(used only to obtain initial fit)

• Simulation estimates:

Unit share

Unit volume
Dollar share
Dollar volume

• Coodness-of-fit calculations for actual vs. estimate

HANDLOADER’S TOOL KIT

(Apple only)

HANDLOADER'S TOOL KIT is an accurate program for
determining the optimum load and complete ballistics
for almost any firearm. Based on a small amount of input
data, you can select the correct powder type (or types)
and powder charge, and calculate the estimated muzzle
velocity and chamber pressure.

Once cartridge loading data have been established, you
may compute the complete ballistics for the cartridge—
including muzzle energy, terminal velocity, terminal
energy, time of bullet flight, bullet wind drift, and bullet
drop for any range. In addition, you may display a
complete trajectory table, showing bullet height in rela¬
tion to line of sight for any range selected. This can be
done for any cartridge for which the muzzle velocity,
bullet weight, and bullet ballistic coefficient are known.

You may average velocities (or bullet weights, or almost
any set of numbers) and find the standard deviation, max.
and min. values, and spread.

If you wish to brush up on the fundamentals of interior
and exterior ballistics, a section on ballistics is also
included in the instruction manual.

You can also study the effect of barrel length (or the effect
of bullet weight and bullet seating depth) on velocity, or
determine the performance and ballistics of a new or
wildcat cartridge without firing a shot. This last feature
alone could be worth many times the cost of the program.

HANDLOADER'S TOOL KIT is menu-driven for ease of
use. It is a must for every serious shooter!

Requires 48K, and one disk drive. A printer is supported.
Price: $79.95 Diskette

PHYSICAL PROPERTIES OF
HYDROCARBON LIQUIDS

(Apple only)

For the first time, the chemical or petroleum engineer
has at his fingertips the ability to calculate quickly the
important physical properties of liquid hydrocarbons,
including viscosity, gravity, and thermal conductivity.
Charts, graphs, tables, log-log plots, and tedious hand
calculations are now replaced by a few simple key¬
strokes on the computer keyboard. This is the only
software package on the market that will predict
reasonable viscosities for cold crude oil and residuum
streams.

LIQUID HYDROCARBONS is divided into three sec¬
tions, with each section covering a different property.

The viscosity vs. temperature portion of the program
uses equations presented in ASTM-D-341, while cor¬
relations for the viscosity of petroleum blends were
obtained from curve-fitting of the blending indices that
appear in Maxwell. Correlations for calculating viscosity
from K and API data were obtained by curve fitting of
data from the API Data Book, TEMA, and the author's
files. '

Specific gravity correlations were obtained by curve
fitting of data that appear in Cameron. Hydrocarbon
liquid thermal conductivities were obtained by curve
fitting of data that appear in Kern.

All portions of the program are menu-driven, allowing
easy access by even the first-time user with only a
minimum of instructions. All calculated results can be
routed to a printer for hard copy.

Requires 48K. Printer optional.

TWO-PHASE PRESSURE DROP
IN PROCESS PIPING

(Apple only)

TPPD allows the design engineer to quickly and easily
calculate pressure drops in process piping for either
single-phase or two-phase flow. You may choose either
the popular Ovid Baker or A. E. Dukler methods for
horizontal pipes, or the widely acclaimed Orkiszewski
method for vertical pipes. For single-phase flow of liquid
or non-compressible gas flow, the pressure drop is calcu¬
lated by the familiar Darcy equation.

TPPD is menu driven, providing flexibility while allowing
easy access by either the experienced computer user or
novice. A multilevel menu structure allows you to quickly
study "what-ifs" for a wide range of pipe sizes or to
change part or all of the input data and study the effect of
flow rates or physical property data on pressure drop for
just about any system. Charts and graphs are not re¬
quired.

With a minimum of input data, you can quickly calculate
the pressure drop for a given nominal pipe size and
schedule; the pipe size for a given pressure drop; the
pressure drop for a range of pipe sizes; or the pressure
drop for a given pipe diameter. Immediate results, along
with a summary of calculated results and input data, are
displayed on the screen and can be printed. Detailed
calculations can also be reviewed or printed.

TPPD covers most common pipe sizes from 2 to 20 inches
and pipe schedules of 10, 40, 80, and 160. Values falling
outside this range can be readily calculated by entering
the actual inside-diameter of the pipe.

Requires 48K of RAM and one disk drive. A printer is
supported, but optional.

SYRSOL ENERGY ANALYZER'

(IBM only)

SYRSOL is a comprehensive and flexible tool for the
energy design, analysis, and simulation of new and
existing buildings of all types and sizes. It calculates
heating and cooling loads, energy consumption, and
operating costs. It uses a dynamic hourly calcuation
model based on ASHRAE (American Society of Heating,
Air Conditioning, and Refrigeration Engineers)
methods for realistic results. The model includes such
factors as building shell, lighting, infiltration, ventilation,
occupancy, solar gains, thermal storage, heating and
cooling equipment, and operating schedules. It per¬
forms a detailed hour-by-hour, zone-by-zone analysis.

Developed on IBM 370 and 4341 mainframes over a
period of 12 years, SYRSOL is a powerful program which
has been well tested in the user environment.

No previous experience with a computer is required.
SYRSOL was designed for busy professionals, not for
programmers.

You prepare the input data files in a completely
interactive manner. You need not know anything about
the format or the order of the input data. The input
query goes through every variable, displays its current
value, and asks you if you wish to change it. You may
change it or just press the <ENTER> key to get the next
variable. The values displayed are read from a reference
file that you specify and can modify for "what-if"
analysis.

The simulation module performs all of the calculations.
For every hour of the day, it goes through every zone,
every surface, and every load, and determines the
hourly heat losses and heat gains. It also calculates the
hourly energy consumption and operating costs.

SYRSOL can handle structures of unlimited size with 80
surfaces and four zones. The software automatically
uses the 8087 math chip if it is present.

Included is a weather database for over 200 cities (You
may add to this.). This database is accessed auto¬
matically by the program.

Here are some of the simulation and report features:

• Detailed energy use and power bill reports (hourly/
daily/monthly/total)

• Building energy-performance analysis

• Perturbation studies

• Flexible operating schedules and capacities for
occupancy, lighting, ventilation, and equipment

• Flexible weekend/day schedule

• Decentralized modular heating and cooling systems

SYRSOL SUN SOURCE™

SOLAR DATA GENERATOR

(IBM only)

SUN SOURCE is identical with the SYRSOL ENERGY
ANALYZER in every sense, with the exception that the
SUN SOURCE deals with a single surface only.

The system requirements for SUN SOURCE are the
same as for SYRSOL. Both packages have the same ease
of use, and same quality, type, and appearance of
output reports. They use the same weather database.

SUN SOURCE can produce more solar data than all the
textbooks and handbooks in a respectable library.

SUN SOURCE can predict solar data for any surface of
any tilt and any azimuth angle anywhere in the northern
hemisphere.

For every hour, every day, and every month of a full
year, the SUN SOURCE can compute the following:

• Total (direct+diffuse+reflected) insolation

• Direct insolation

• Direct normal insolation

• Diffuse insolation

• Reflected insolation

• Solar altitude angle

• Solar azimuth angle

• Solar incidence angle

SUN SOURCE produces complete and self-docu¬
menting tabular and graphical reports giving hourly
values; half-day, full-day, and monthly totals.

HEAT LOGS

(Atari, Apple, and CP/M only)

HEAT LOSS uses ASHRAE (American Society of Heating,
Refrigeration, and Air Conditioning Engineers) methods
to calculate the heat losses through various parts of a
building: roof, walls, doors, etc. Window, door,and lower
areas are automatically subtracted from wall areas, and
the heat loss for each element is calculated and summed
for room and building totals. Room infiltration and ventil¬
ation loads are also calculated, along with the overall
building heat-loss coefficients required by some state
energy codes.

HEAT LOSS is intended to be used by heating design
engineers, building contractors, architects and engineer¬
ing students. While most aspects of the design process
are explained, additional information from a source such
as the ASHRAE "Handbook of Fundamentals" would be
required for actual design work. For example, "R" values
are needed.

HEAT LOSS provides for storing and retrieving data,
reviewing and changing of individual rooms or room
elements, and printing out results. It will handle up to two
hundred rooms on a 48K machine. Printer output is very
general—all 40-column and 80-column printers will
work.

SOLAR HEAT GAIN

(Apple and Commodore 64 only)

SOLAR HEAT GAIN is intended to be used as a design
tool for anyone interested in the effects of the sun on
the heating and cooling of buildings.

SOLAR HEAT GAIN has five options. The insolation
option calculates gain through unshaded glazing. The
overhang option calculates gain through a window or
windows shaded by an overhang. The shading option
calculates gain through a window shaded by a wall on
one side of the window, by walls on both sides of the
window, or by a wall or walls in combination with an
overhang. The egg-crate option calculates gain through
a deeply recessed window or through a window shaded
by an egg-crate shading device. The external shading
option determines whether an object such as a tree or
wall is shading the wall of a building.

You enter specific information which is explained in
detail in the manual. The program displays the
information entered on the screen so that you can
check it for mistakes. If correct, the calculations are
made and displayed on the screen.

Examples are given for the insolation and overhang
options which show how they are used. A section that
gives some tips on designing shading devices is also
included.

SOFNET

(CP/M, IBM, TRS-80, and Apple only)

Liquid Pipeline Network Analysis

Apple description; TRS and others very similar.

SOFNET is a general purpose liquid pipeline network
analysis program designed for the Apple personal com¬
puter system. It is written in APPLESOFT BASIC with
machine-language subroutines for greater speed. The
hardware requirements include a minimum of 48K
memory, one disk drive, and an optional 80-column
printer for permanent copy.

SOFNET is a powerful modeling tool for system planning
and analysis which lets you tackle virtually any type of
network configuration. Network data files may be
created, edited, and stored on diskette using the Apple's
built-in APPLESOFTeditingfeatures. When executed, the
input data file is interactively requested by the system.
An internal data checker searches for data errors and
omissions. Once verified, the program indexes all nodes
and associated connectors and solves the series of flow

equations by an interactive link node technique. Solution
tolerance is set by the user. Once solved, results are
displayed on the screen and, if desired, printed. Results
can be saved for use in another simulation and you can
play "what if" by inputting new values, recalculating, and
then displaying the new results.

Network elements such as pipelines, pumping systems,
valves, force mains, and storage facilities can be specified
to accurately represent the physical system being
modeled.

SOFNET can treat:

- Up to 150 system nodes and determine pressure and
external flows at each point.

- Flow through up to 150 connecting elements.

- Hazen Williams equation.

- Mannings Equation.

- Pumping systems.

- Check valves and other head loss elements.

- Up to 10 pumping stations including pump character¬
istics.

ROOTS

(available for all computers)

If you want to determine the zeroes of a polynomial having
real coefficients, ROOTS is the program for the task
ROOTS employs a relatively little known algorithm described
in the computer mathematics literature several years ago.
This algorithm iteratively seeks all the roots simultaneously.
The convergence is cubic (and therefore rapid) and very
stable, requiring no explicit initial guesses from the user.
Accuracy is usually within two digits of the precision of the
BASIC employed. In addition to displaying the calculated
solutions, the program also shows the results of substituting
those values into the original polynomial. Convergence
failure is highly unlikely and, if it occurs, it is generally
limited to special multiple (M-2) roots. Any order polynomial
may be treated. Price; $15.95 Cassette

CALFEX and CALFEX G/T

(Apple and IBM)

Forget your calculator, CALFEX and CALFEX G/T are here!
They form a general-purpose menu-driven equation pro¬
cessor for engineering and scientific analysis. Now you
can do calculations that used to take hours in only
minutes. CALFEX does for engineers what the popular
spreadsheet programs do for businessmen. You provide
the equations and CALFEX does the rest. Labels or names
for variables are easily included. Up to 10 sets of values
for the independent variables can be saved.

From the menu page showing all the inputs, any value
may be easily changed by moving the cursor. One key¬
stroke then displays all the calculated answers. The
powerful Variable Exchange feature lets you. force an
answer to a given value by varying any input, without
rewriting anything. It uses an iteration process that also
lets you solve for variables which are difficult or im¬
possible to solve for analytically. For example, you
might specify the values of certain dependent variables to
determine the independent variable (specify deflection
and find force).

ADDITIONAL FEATURES:

• Graphs and Tables: CALFEX G/T contains built-in
graphics to allow plots of your results with a minimum
of effort. Includes autoscaling if desired and tables of
values for the plotted points. You can also plot up to 3
lines on a graph by letting a third variable take on 3
distinct values. Works with any printer. Choice of
linear, log, or semilog plots.

• Maxima and Minima. Can be found automatically.

• Simultaneous equations. Up to 10.

• Numerical Integration.

• Array or Simple Variables. Up to 120 inputs and 120
outputs.

• Access to BASIC. Normally you just add your
equations but, if needed, you have full access to
BASIC programming, including reading or saving data
files, adding your special programming, etc.

• Organized and Documented Programs. Other users
can now follow your programs.

CALFEX is easy to learn, even if you have never used a
personal computer. It is extremely useful for design
optimization modeling. CALFEX is supplied with a
thorough manual and demos. Also included is CALFEX
G/T which is described as follows.

CALFEX G/T expands the capabilities of the basic CALFEX
program. With graphs you can easily see the general trend
of how one variable depends on another. Then you can
get a table of the exact values for all the plotted points if
desired. If, for example, you are trying to optimize a
design, the graph shows the trend and the table gives the
values so you can quickly get a feel for how the variables
interact. The CALFEX G/T package speeds up the process
of finding useful solutions to your problems.

• EASY TO USE: The graph is automatically scaled and
labeled with a minimum number of inputs from you.
The whole program is designed for ease of use.

• LINEAR, LOG, OR SEMILOG PLOTS are easily created
by simply choosing the scale for each axis.

PIPELINE PRESSURE LOSS

(Atari, CP/M, and IBM only)

PRESSURE LOSS calculates the pressure head loss in
simple piping systems, such as found in plumbing and
heating. The longest path (greatest resistance) is selec¬
ted, and the corresponding head loss calculated. This
gives the greatest head a pump has to deliver to supply
the demand.

In operation you select the material (copper, PVC, or
schedule-40 steel) and the max/min unit head loss
(default is the ASHRAE recommended 100-500 milli-
inches/ft.). You also supply the initial flow, the number of
elbows, gates, globe and check valves, line flow and
branch flow tee's. The program then determines the
proper pipe diameter, calcualtes the unit head loss and
total loss.

At the beginning of each segment you can add or delete
from the flow, or specify a direct loss (e.g., the rated drop
through a coil). The program uses data from ASHRAE
charts and employs the system head curve relationship to
determine the loss for trial pipe diameters until a loss in
the specified range is found.

The program is accurate in the loss range of 100-500 milli-
inches/ft., and can be used outside that range with less
accuracy.

Requires 48 K.'

MECHANICAL ENGINEERING #1

(Apple and IBM)

A collsction of programs for uso wrifeh CALFEX

This is a collection of mechanical engineering programs
for use with the general purpose analysis program,
CALFEX.

These programs can save you considerable time and
effort in analyzing problems. They are truly a bargain on a
cost-per-program basis and, since all utilize the basic
CALFEX program, the format is uniform and easily under¬
stood. The programs are a valuable addition to any
mechanical engineer's library.

These programs were written by professional engineers
for real-world problem solving and design optimizing.
Some of the solutions presented here will not be found
elsewhere. Most are adapted from well known problems.
They are sufficiently documented so that you can check
the underlying theory if necessary, or alter it to suit
special purposes. All are written in BASIC and program
printouts are included to facilitate detailed review.

All allow the powerful Exchange Variable option, so you
can interchange a dependent variable for an independ¬
ent variable to reverse their roles.

CONTENTS

Applied Math

FOURIER SERIES for up to 59 pairs of input values,
resulting in up to 59 coefficients of sine and cosine terms.
A second program does the same job and, in addition,
calculates how well the resulting Fourier Series fits the
given data.

Stress and Strain

BEAMS WITH TRAVERSE LOADS: This program contains
all the 6 combinations of simple beam-end conditions
and 7 kinds of traverse loads, moments, and imposed
distortions of Table 3 of Formulas for Stress and Strain, 5th
Edition, Roark and Young (McGraw-Hill Book Co.). Up to
37 individual loads, moments, and distortions at 37
locations may be simultaneously imposed and the pro¬
gram sums up the result. The CALFEX exchange variable
feature allows maxima and minima to be found for stress,
moment, deflection, etc.

HELICAL SPRINGS, GENERAL This program calculates
axial, torsional, and lateral bending stiffness and resonant
frequencies, along with the usual spring parameters, for
round or rectangular wire. Some of these results have not
been previously available. In particular, buckling loads
are calculated by a more complete theory than has been
generally used.

HELICAL SPRINGS, SIMPLE: This is similar to the above
but omits a number of the more usual outputs. It runs
faster and is a little easier to use, vyhen it is adequate.

HELICAL SPRINGS, NONLINEAR: This follows the
special theory reviewed on pages 320 and 321 of the
Roark and Young book, giving a more precise relation
between load and axial displacement.

BEAMS WITH END LOADS AND SIDE LOADS: This is
capable of almost exactly the same results as Beams With
Traverse Loads but with end loads of tension or com¬
pression. It contains the essential parts of tables 10 and
11 of the Roark and Young book for all 6 beam types. For
anyone end load, up to 55 traverse loads can be applied,
and the results are summed up.

Fluid Flowf

DUCT FLOW calculates pressure drop, mean velocity,
Reynold's Number, etc., for incompressible flow for
round or rectangular ducts or pipes. For air and water,
viscosity and density are calculated automatically if you
enter the temperature and pressure. Roughness is one of
the inputs.

Dynamics

DISK-SHAFT VIBRATIONS: Resonant frequencies are
computed for a system of disks and shafts, for as few as 2
disks and 1 connecting shaft or as many as 59 disks and 58
shafts. For a given driving frequency and amplitude on
one end, the amplitudes of response of each disk may
also be determined.

IBM version requires 96K; Apple version requires 48K.
Needs CALFEX to operate.

SECTION PROPERTIES

(Atari version)

Structural/mechanical design and stress analysis
often requires calculation of the strength and stiff¬
ness properties of various structural cross sections
to determine the capability of the sections to with¬
stand axial, bending or torsional loads. SECTION
PROPERTIES greatly speeds and simplifies the task
of determining these properties, particularly for
complicated or irregular sections.

This program is entirely menu driven and self
prompting, with extensive error trapping and
correcting to help prevent the necessity of restarts.
The sections are presented graphically on the screen
to increase usability and reduce the possibility of
incorrectly defined shapes.

SECTION PROPERTIES provides solutions for cross
section area, location of section centroid, moment
of inertia, section modulus, radius of gyration,
product of inertia, polar moment of inertia, principal
major and minor moments of inertia and the angle of
the principal major axis. Printer options allow the
user to obtain a printer trace of the input data, a
screen dump of the plotted section or a hard copy of
the results. Includes 45 page manual. Requires 24K
(cassette) or 32K (disk). Printer optional.

Price: $39.95 Cassette

SECTION PROPERTIES

(TRS-80, CP/M, and IBM only)

SECTION PROPERTIES will calculate mechanical prop¬
erties for virtually any structural cross section. You may
determine the area, centroids, moments of inertia,
section moduli, and radii of gyration about two given
perpendicular axes of the section. You may also
evaluate the angle of the principal axes, moments of
inertia, and radii of gyration about the two principal
axes. Output values may be recorded from the screen or
listed on a printer.

The cross section may be composed of rectangles, radial
segments, and special sections with known properties,
with a limit of 20 of each type. Rectangles may be
oriented at any angle. Radial segments may be a solid
bar, a circular sector, a round tube, or a shell segment.
Special sections may be any for which the properties are
known, including all the standard rolled sections given
in the steel manuals.

SECTION PROPERTIES is an interactive program with
menus for options and screen prompts for data entries.
It was designed to be "user friendly" with screen help
information, editing, and data backup features. Section
input data may be stored for later editing and use.

Requires at least 48K of RAM. A printer is supported,
but optional. Includes a 30-page manual.

ANALYSIS OF CONTINUOUS BEAMS

(TRS-80, CP/M, and IBM only)

ANALYSIS OF CONTINUOUS BEAMS (ACB) is a
program for analyzing determinate and indeterminate
beam structures. It calculates joint displacements and
rotations, member end shear forces, bending moments,
and section top and bottom stresses. Loading may be
defined by concentrated loads and moments, and
member-uniform and linearly distributed loads. ACB is
also capable of analyzing support settlement.

Connections between the members may be either rigid
or hinged. Moments of inertia and section moduli may
be different for each member. The limits are 40
members and 60 degrees of freedom. The number of
load cases is not limited. Joint locations (displacements)
are given not only at supports, but also at concentrated
loads and moments, the start and end of member-
distributed loads, and at any other location for which
output results are needed.

ACB is an interactive program with screen menus for
options and prompts for data input. It is designed to be
"user friendly" with screen help information, editing
and backup features, and minimal data preparation. You
also have the option of storing the beam data for later
editing and running.

ACB and DYNACOMP's BEAM DEFLECTION are quite
different programs aimed at different applications,
though there is some overlap.

A brief comparison is shown below:

Capabilities in ACB not available (or limited) in BEAM
DEFLECTION:

• Bending moments can be specified at each member
joint

• Composite beams having 40 members can be
defined. This allows for abrupt changes in modulus,
loading, etc. BEAM DEFLECTION approximates abrupt
changes.

• Much more detailed beam description.

• Hinging between members (versus pinning in BEAM
DEFLECTION).

• More output stations, resolution.

Capabilities in BEAM DEFLECTION not available in
ACB:

• Spring supports, elastic bed.

• Much less input required (e.g., degree of freedom
information at each joint not required).

• Solution not by segments, but by integration over
continuous beam.

• Plotting of deflection and stress.

• Stress evaluation at any specified distance from
neutral axis.

The differences between ACB and BEAM DEFLECTION
are largely the result of a difference in the mode of
solution.

Includes a 35-page manual. A printer is supported, but is
not necessary (though recommended). Requires at least
48Kof RAM.

$69.95 (diskettes), $73.95 (8-inch CP/M Disks). Sorry,
no further discounts off the package price (e.g., 10%-
20% quantity discounts) are permitted.

BEAM DEFLECTION

(Available for all computers)
disk/diskette only

BEAM DEFLECTION is the first in DYNACOMP's new
series of structural analysis software packages. It consists
of two programs. The first program permits the develop¬
ment of data files which describe the problem. For
example, the ends of the beam may be pinned, clamped
or free. The beam may be uniformly supported by an
elastic bed, or held up by springs variously placed and
having differing spring constants. The elasticity and
cross section of the beam may vary along its length. The
load may be uniformly distributed or it may include
discrete forces. The beam may be pinned at various
points along Its length. And soon. All this information may
be easily entered and edited using the data input
program.

Following this the analysis program is called. The calcu¬
lated results are the stress and deflections of the beam,
both in numerical and graphic form. Since the input data
is saved, cases may be easily re-run with modification,
thereby permitting iterative design.

The documentation which comes with BEAM DEFLEC¬
TION clearly shows how to use the software. In addition,
three text problems are described and demonstrated to
ensure that you understand how to use the program. Also,
helpful theoretical information is supplied in the
appendix.

prior to June 15,1984, please note that some improve¬
ments have been made to the interpolation routine. You

ANALYSIS OF PLANE FRAMES
ANALYSIS OF PLANE TRUSSES
ANALYSIS OF PLANE GRIDS

(TRS-80, CP/M, and IBM only)

ANALYSIS OF PLANE FRAMES (APF) is designed to
analyze determinate and indeterminate plane frame
structures. APF calculates horizontal, vertical, and rota¬
tional displacements at the joints, as well as axial forces,
shear forces, bending moments, and section top and
bottom stresses at the member ends. Loading may be
defined as concentrated loads or moments and/or
member-uniform or linearly distributed loads in either
the horizontal or vertical directions. APF is fully capable
of analyzing a support settlement case.

Connections between the structure members may be
either rigid or hinged, and the properties may be different
for each member. Supports may be located at any
member end and may have restraints in the horizontal,
vertical, or rotational directions. The structure limits are
20 members and 50 degrees of freedom. There is no limit
on the number of load cases.

ANALYSIS OF PLANE TRUSSES (APT) issimilarto APF, but
is specifically suited to analyzing determinate and in¬
determinate plane truss structures. APT calculates hori¬
zontal and vertical displacements at the joints, and axial
forces and stresses in the members. Loading is defined as
concentrated joint loads in either the horizontal or ver¬
tical direction. APT is also capable of analyzing a support
settlement case.

Supports may be located at any member end and may
have restraints in either the horizontal, vertical, or both
directions. The structure limits are 60 members and 60
degrees of freedom. There may be up to 60 different
member areas. There is no limit on the number of load
cases.

ANALYSIS OF PLANE GRIDS (APG) is the third member
of the series and is used for analyzing plane grid struc¬
tures. APG calculates out-of-plane displacements and x
and y axis rotations at the joints, as well as shear forces,
torsion moments, bending moments, and section top and
bottom stresses at the member ends. Loading may be
defined as concentrated loads or moments and/or
member-uniform or linearly distributed loads. APG is also
capable of analyzing a support settlement case.

Connections between members may be either rigid or
hinged and properties may be different for each member.
Supports may be located at any member end and may
have restraints in the z displacement, and xor y rotational
directions. The structure limits are 20 members and 50
degrees of freedom. There is no limit on the number of
load cases.

APF, APT, and APG are interactive programs with screen
menus for options and screen prompts for data input.
They are designed to be "user friendly" with screen help
information, editing, and "back-up" features, and require
minimal data preparation. Naturally, you have the option
of storing frame data for later editing and usage.

Accuracy has been checked by comparison of full
capacity results with similar runs using MSCPAL Finite
Element Analysis.

Requires at least 48K (TRS-80), 64K (CP/M, IBM), and
BASIC. A printer is supported but not necessary.

BEAMS 1-2-3

(IBM only)

BEAMS 1-2-3 is designed to be used by both engineer¬
ing students and practicing engineers to design, analyze,
and study the reactions of many types of beam-loading
configurations. It uses analytical solutions and the
principle of superposition (finite elements, etc., are not
employed) to very quickly and accurately determine
the reactions (and deflections, etc.) under 60 com¬
monly used beam-loading configurations.

Three types of beams may be examined: simply
supported, cantilevered, and fixed ended. The cases
covered include 29 statically supported and 31 static¬
ally indeterminate (usually the difficult ones). You may
calculate and display (or print) all values of the shear,
moment, deflection, bending stress, and shearing stress
in three ways:

• For design, all maximum values are calculated.

• For analysis, all values at any location may be
calculated.

• For study, all values at equally spaced points may be
calculated.

Calculations may be done in any of four units (English,
kilo-English, Metric, kilo-Metric). Also, any material may
be used, or you may choose from a menu of seven
common materials (A-36 steel, cast iron, aluminum-
6061, brass, bronze, Douglas fir, structural concrete).

The types of loading conditions include multiple
concentrated loads, uniformly distributed loads, and
pure moments. Also, spring supports may be analyzed.

Because the calculations are based on analytical
equations, the results are obtained very quickly and
with very good accuracy.

One of the particularly nice features available in BEAMS
1-2-3 is that you are also given a diagram showing the
loading conditions and reactions. This is very helpful in
visualizing and organizing your results. These diagrams
may also be printed if your printer is capable of high-
resolution screen dumps.

BEAMS 1-2-3 is ideal for the practicing engineer who
wants to quickly and easily get results, for the student
wanting to check homework, for the educator who
wishes to develop assignments or demonstrate beam
calculations, or for anyone interested in the solution to
analytical beam problems.

Requirements: 128K RAM, BASICA (graphics BASIC),
IBM graphics card. An 80-column (or wider) printer is
supported, but not necessary. To get printed beam
diagrams, a printer capable of hi-res screen dumps is
needed.

ANALYSIS OF

THREE DIMENSIONAL FRAMES

(CP/M, IBM, and TRS-80 only)

3-D FRAMES is designed to analyze three-dimensional
frame structures. It calculates displacements and
rotations in three directions at each joint and axial
forces, shear forces, and bending moments in two
directions, as well as torsional moments and combined
stresses at each member end. Stress output is optional
for each member and you may have up to four locations
oh a member cross-section with combined axial and
bending stresses in two directions. This option is
excellent for use on unsymmetrical members. Loading
may be concentrated loads or moments and/or member
uniformly distributed loads.

Connections between the structure members may be
either rigid or hinged, and the properties and stress
locations (0-4) may be different for each member.
Supports may be located at any member end and may
have restraints in the x, y, and z displacement directions
and in the x, y, and z rotational directions. The structure
limits are 20 members and 60 degrees of freedom.
There is no limit on number of load cases.

BEAM-COLUMN ANALYSIS
2nd ORDER FRAME ANALYSIS

(IBM, TRS-80, and CP/M only)

BEAM-COLUMN ANALYSIS and 2nd ORDER FRAME
ANALYSIS are user-interactive programs for solving
multiple-span beams and columns and plane-frame
structures in the elastic range, and include the
secondary effects of deflected shape under load.

A structure deforms as load is applied, changing
geometry and the stiffness matrix. Conventional linear
analysis, programs assume small deformations and
neglect the effects of changing geometry. For structures
having long spans or carrying large axial forces, results
may be inaccurate using a conventional linear analysis
approach.

BEAM-COLUMN ANALYSIS and 2nd ORDER FRAME
ANALYSIS use non-linear elastic analysis theory, in¬
cluding the P-Delta effect, and work for tension as well
as compression axial loads. They are intended for users
with a basic knowledge of structural analysis, but were
designed to be "user friendly", requiring minimal data
preparation.

BEAM-COLUMN ANALYSIS can solve multiple-span
beam structures with up to 40 members and up to 100
degrees of freedom. SECOND ORDER FRAME
ANALYSIS can do the same for plane, frames.

Connections between members may be either rigid or
hinged. Concentrated loads and moments are accepted
with no limit on the number of load cases. The analyses
use an iterative approach, regenerating the stiffness
matrix and giving results for each iteration. These values
converge to a final solution if the structure is stable.
Divergence indicates that the structure is unstable
under the given loading.

You may select printer or screen output. Output
includes member end displacements, rotations, axial
forces, shear forces, bending moments, and section top
and bottom stresses.

Both programs are menu-driven and use screen
prompts for data entries. You may edit, store, and recall
data. The manuals (B-C, 46 pages; FRAMES, 48 pages)
include careful descriptions and examples.

Requires 64K (IBM and CP/M), 48K (TRS-80). A printer

LINEAR PROGRAMMER MINIMAX

(CP/M, IBM, and TRS-80 only)

LPM is a more powerful version of DYNACOMP's
LINEAR PROGRAMMER which can treat over- and
under-constrained problems, maximize an objective
function, and solve simultaneous linear equations. It
uses the fast and efficient Khachian algorithm to obtain
the solution (or nearest solution) to the matrix
inequality:

A X < B

For example, you might wish to solve the following set
of inequalities:

Xi > 1

’ Xa > 1

Xi + Xa < 2

These can be put into the desired matrix form (the
manual describes how this is easily done), and solved by
LPM. In this case an exact answer exists (barely!) with
Xi — 1, Xa — 1. However, what if you wanted to
consider the same equations with Xi 4- Xa < 1.8?
LPM will also "solve" this case and give you the closest
(least violation of the inequalities) solution. This is
something most linear programming routines cannot do!

LPM also handles linear programming problems in
which the goal is to minimize or maximize an "objective
function" which is a linear combination of the variables.
For example, consider the following problem:

Xi < 3
Xa < 7
Xi + Xa < 7
6Xi 4- 7Xa = B

Here the first three inequalities, might describe manu¬
facturing constraints, while the fourth might describe
the profit, B. What is B? In this case LPM will iteratively
seek B and give B = 49, with Xi = 0, Xa = 7.

Finally,_by setting up the problem with AXB^and
AX > B, the simultaneous linear equation AX = B can
be analyzed. The advantage to using the Khachian
algorithm here is that the solution is found by iteration,
greatly reducing round-off error.

LPM includes very easy data entry, storage, retrieval,
and editingr If desired, you can also send your data
tables and results to a printer.

Although LPM can handle up to 100 constraints in 20
variables, it is really more applicable to problems half
that size or less. For more than that, a fast mainframe
program is suggested. For solving simultaneous linear
equations, the limit is 18. ^

THE SUPERSOFT OPTIMIZER

(Apple, TRS-80, CP/M, and IBM only)

In brief, THE OPTIMIZER is a disk-based linear
programming system for solving business problems.

In the strict sense, linear programming is a deterministic
method of analysis used to choose the optimum course
of action. In a business sense this allows a manager to
decide on the appropriate course of action from among
many alternatives. Routine decisions involve many
tradeoffs and these can normally be grouped into two
categories: constraints and objectives. For example, in
choosing a new car, a consumer is faced with constraints
of his budget opposed to his desire to maximize the
value of the car that he buys.

Many business problems lend themselves to being
formulated as trying to optimize an objective subject to
some number of constraints. An investment broker, for
example, may be trying to maximize his return subject
to the risks his client is willing to take, or a manufacturer
may be trying to minimize cost in the production of a
series of products.

THE OPTIMIZER does not require that the user
understand any higher mathematics. In fact, the
solution of problems by this program can be undertaken
strictly from a common sense point of view. The
program can be used to solve problems in the areas of:
production scheduling, personnel assignment, product
buying, product pricing, personal finance, and many
more. The problems which can be solved are limited
only by the insight of the user. The importance of this
type of problem solving is attested to by the fact that
most large businesses have full time programming staffs
which work only these types of problems.

THE OPTIMIZER also provides sensitivity analysis
including the shadow price (dual variable), range of
resources over which the shadow prices are valid, slack
quantities (helpful in further improving efficiency or
costs), and stability (how sensitive is the solution to the
Objective function coefficients).

The manual is well written and contains tutorial
information as well as examples.

Requires at least 48K RAM; a printer is optional. The
Apple and TRS-80 versions are in machine language; the
TRS-80 version requires two disk drives.

SuperSoft's list price is $200. DYNACOMP's price is
$169.95.

DYNACOMP's pricing policy is simple: for software
published by DYNACOMP, we survey what is currently
available and try to price our products at 50% to 75% of
that; sometimes even less.

For products we distribute (which are published by
other companies), we try to give you a direct discount of
10% to 20%. Even when we can't give you a direct
discount, you can use our 10% (3-4) or 20% (5 or more)
quantity discounts to reduce your costs substantially.

In short, we try to give you good value for what you pay.

Which way are the prices going? If you have been
following DYNACOMP's prices for the past eight years,
you may have observed that they have generally stayed
either the same or increased slightly (roughly 10 %),
except in the "games" category. The prices for games
have fallen significantly in some cases (e.g., arcade
games). Also, DYNACOMP has taken the approach of
combining several games into one package, thereby
increasing the value/price ratio.

PROCESS ENGINEER'S
CONVERSION KIT

(Apple only)

PROCESS ENGINEER'S CONVERSION KIT enables you
to convert between units commonly used in the process
industries.

Measurements of temperature, pressure, mass, density,
and other process parameters are easily converted be¬
tween standards. This is done without the tedium of
researching and entering formulas. Convenience is en¬
sured by a menu-driven spreadsheet screen format.
Extensive error checking makes certain that no out-of¬
range or illegal vanues can be entered.

Most conversion tables published in reference books are
deficient in two areas: they often do not cover the
required range, and the resolution is usually too coarse,
requiring interpolation. PROCESS ENGINEER'S CON¬
VERSION KIT lets you create your own tables, the way
you want them! Your table can be completely specified in
the time it takes to do a single calculation on a hand
calculator.

PROCESS ENGINEER'S CONVERSION KIT actually con¬
tains ten programs, each one dedicated to certain cate¬
gories of standards conversion. While beingdesigned pri¬
marily for engineers, technicians, operators, and pro¬
duction staffs in the process industries, these programs
may be easily adapted to many other uses ranging from
commercial exchange rate to converting Cordon Bleu
recipes written in metric units.

ROAD ENGINEERING

(IBM only)

ROAD ENGINEERING consists of two programs for road
design and construction. They are very user friendly.
There are no commands to learn and you simply answer
the prompts as they appear on the screen. These pro¬
grams have been in use for more than six years, and have
been fine-tuned to be both productive and easy to use.

CONSTRUCTION CURVES computes curve details from
the deflection angle and the radius or tangent. Results are
the deflection, radius, arc, chord, and external. You can
print a field layout for staking at any station spacing and
for any offset desired. The printout lists the deflections,
the long arcs and chords, and the short arcs and chords at
each station.

ROAD GRADES computes and prints a continuous list of
design center and gutter elevations at any station
spacing, for any road width and X-fall% specified. You can
enter the station and elevation of numerous points, with
or without vertical curves. Automatically saves data to
disk for later revisions.

Requires IBM PC, 64K, one drive, and an 80-column
printer.

HINT

(cassettes)

If you are experiencing tape loading problems, the tape
may be unevenly wound and binding. To free it up,
sharply slap the flat side of the cassette down on a hard
surface. This forces all of the tape against one side of the
housing evening up the edges and allowing it to run
smoothly again.

ENGINEERING COLLECTION #1

(CP/M and IBM only)

Here is a collection of ten programs|which should be
included in any engineer's, library software:

1. ANTENNA PLOT: You may specify up to 100
array elements and their locations.

2. BODE PLOT: You specify the poles and zeroes,
the program plots and lists the response.

3. CONVOLUTION: Input two waveforms and get
the convolution, both plotted and listed.

4. FOURIER PLOT: Produces the discrete Fourier
transform of a set of data. Plots and lists. You may
also specify the number of harmonics to be
computed, and reconstruct using these harmonics.

5. NUMBER CONVERSION: Converts between
decimal, binary, octal and hexadecimal.

6. REACTOR SIMULATION: Based on reactor
kinetics equations found in NUCLEAR ENGI¬
NEERING HANDBOOK (by McGraw-Hill).

7. CONTROL SYSTEM SIMULATION: Simulates a
second order closed loop control system.
Responses may be listed, saved and plotted.

8. SPLOT: Plots sets of X, Y data on 80 column
printer.

9. PPLOT: Similar to SPLOT, but for dot matrix MX-
80.

10. SCPLOT: Similar to SPLOT, but plots on screen.

Each of these programs may be called from the main
menu provided on the DYNACOMP diskette, or
each may be incorporated into you own BASIC
programs (they are written in BASIC). Even if you do
not have an immediate application, this collection
has considerable education value. Sample data sets
are included. Supplied with 62 page manual showing

LADDER NETWORK

(TRS-80, CP/M, and IBM only)

LADDER uses the technique of describinga network
as a series of cascaded two-ports. This representa¬
tion is sometimes pictured as a "ladder". Each two
port is described individually, from load to source, in
a data file generated by following the program
prompts. Each element type and value is then read
and an "ABCD" matrix for each element is generated.
This matrix describes the transfer characteristics of
the two-port element and the multiplication of two
or more"ABCD" matrices will yield the total transfer
characteristic of the series of two-ports. LADDER
uses matrices (with complex numbers) to describe
the transfer characteristics of passive networks
(capacitors, resistors, inductors, and transmission
lines). The network architectures may include parallel
and series branches to any depth, open and shorted
stubs, and two parallel or series ladder networks. All
elements (except resistors) require a quality factor
or loss figure be defined at a single, operator
defined, frequency. With this information, the
network' responses are determined using "real
world" components. This program can handle
networks consisting of up to 50 two-port elements.
Requires 32 K.

ACTIVE CIRCUIT ANALYSIS PROGRAM
(ACAP)

(available for all computers except North Star & Atari)

ACAP is an active and passive circuit analysis program. It
can be used to solve for the node voltages of a network.
The circuit elements which can be analyzed by ACAP are
resistors, capacitors, inductors, voltage sources, current
sources, and a voltage-controlled current source To describe
a circuit to ACAP, you enter it in a simple algebraic form.
Using the ACAP editor, you may easily enter and change
the element descriptions. You may also save the circuit
description on tape/diskette in order to later recall it

The circuit description must have nodes numbered 0
through N when there are (N+l) nodes in the circuit The
maximum number of nodes in a circuit description is 40.
The program outputs node voltages referenced to nodeO,
or outputs node gains in db referenced to a specified node.
“nT through "n4" are node numbers. "Value” is the
component value, "%-tol." is the percent tolerance of the
component (%-tol. is optional). The r-value and i-value are
the source values: r-value is the real part and i-value is the
imaginary part (i-value is optional).

ELEMENT FORMAT

Resistor

Note that transistors/amplifiers can be simuidtea with the
voltage-controlled current source. As you can see from the
above element description, ACAP includes an analysis of
the uncertainty in the circuit response due to variations in
the components. Some of the commands available to
ACAP are:

DB - output results in decibels: DB <node 2>

F - frequency to be used: F<f initial, f final, f step>
PRINT - Print node voltages: PRINT <n>, n,, n., n., rv>
REPEAT - Repeat calculation (to build statistics)

STAT - Calculate mean and standard deviation at nodes:

STATCn,, n,, n,>

The STAT command uses the % tolerance values and the
REPEAT number to build a MONTE CARLO description of
the range of values at a node. The F command permits an
analysis of the frequency response of the circuit

As you can imagine, it is difficult to describe ACAP in the
limited space of a catalog. However, you can appreciate its
powerf

LOGIC SIMULATOR

(Apple and IBM only)

There are two ways to test a circuit design: build a
prototype and experimentally examine all the input/
output conditions, or probe the circuit's performance
using LOGIC SIMULATOR. The latter approach is faster
and less expensive, as well as being more amenable to
rapid design iterations.

The circuit elements which may be treated by LOGIC
SIMULATOR include the following,-

• Multiple Input AND, NAND, OR, NOR, EXOR and
EXNOR Cates

• Inverters

• J-K and D Flip:Flops

• One Shots

Inputs may be clocked in with varying clock cycle lengths
and displacements. Change of state delays may be intro¬
duced to test for real life glitches and race conditions. The
response of the system is available for display every clock
cycle and, at the user's option, a timing diagram for any
given set of logic nodes_ (including the inputs) may be
simultaneously plotted using HIRES graphics.

All this is accomplished with a simulation language (operated
through BASIC) designed specifically for this task. This
language is both easy to learn and quick to use.

LOGIC SIMULATOR is supplied with a 9 page instruction
manual and is ideal for use in the classroom where the
student may design logic circuits and quickly test them.

WIREMAP

(CP/M, IBM, and TRS-80 only)

WIREMAP is designed to allow electronic circuits
and schematics to be computerized for the purpose
of generating parts lists, wire lists, and signal lists.
These lists may then be used for the purposes of
production, debugging, trouble shooting, and
documentation of the circuit. Wl REMAP is especially
useful for prototype, wire-map, and point-to-point
circuitry, since the signal listing may be used as a
guide to correctly wiring the circuit. The program
also provides an easy means of checking for errors.
Any open signals will be flagged during a wirelist
printout. Includes easy to use data editing features.

LOGIC DESIGNER

(North Star, Osborne and CP/M only)

LOGIC DESIGNER is an interactive digital design program
(not a simulator) which greatly speeds up and simplifies
digital hardware desiga Error-free solutions of combinational
logic problems having between 2 and 8 input variables are
obtained quickly and easily. Previously, such capability has
been available only on large mini and mainframe computers.

The program prompts for a user-defined truth table
(including"don't care" conditions) and reduces the input
data into two boolean logic equations. Either equation can
then be directly and easily converted into digital hardware.
The program asks for all necessary information and checks
the responses for format errors. An entry editor is provided
to allow corrections. Facilities are provided for modification,
addition, or deletion of entries. You may also view the
entries on command. The editor provides a fast and easy
method of correcting errors without re-entering the entire
data base.

Due to large amount of data reduction required for
complex problems, speed is very important The reduction
process is therefore accomplished with fast and efficient
assembly language code. Without it, the program run time
would be greatly increased. Manual: 15 pages.

Requires 16K of program memory and an 8080/Z80
CPU.

Not available for Canon or Heath/Zenith.

MICROCOMPUTER
LOGIC DESIGN PROGRAM

(Apple and IBM only)

MICRO-LOGIC was created to enhance the productivity
of electronic digital design by providing an interactive
drawing and simulation system, allowing you to quickly
design and predict the performance of a circpit without
your having to actually build it.

This software product will help you to:

# Draw a logic diagram directly on the CRT screen.

• Run atimingsimulation of the network respondingto
user-defined input sources.

It's like building a breadboard and hooking up signal
sources and logic analyzers to see what happens ...
except that it's faster.

Logic diagrams are drawn directly on the screen using the
Designer program. Using the keyboard commands, you
move the drawing cursor around on the screen adding or
deleting gates. Each time you add a gate, the system
draws it at the cursor position. Drawing interconnecting
lines and contacting gate input and output nodes using
the PLOT and CONTACT commands allows you to create
any type of logic network. Completed logic diagrams can
then be saved in a diskette file.

When the drawing is complete, the sytem automatically
prepares the netlist needed for the simulation.

Users may create their own gates. Up to 36 different 5-
input functions may be defined and subsequently used
in any network. Gate characteristics include name, delay,
64-state truth tables, and input/output clocking.

FILTER ANALYSIS

(Apple only)

FILTER ANALYSIS calculates the effective attenuation of a
electrical filter composed of passive elements. The effective
attenuation is the ratio (in decibels) of the power delivered
(to the load) to the maximum power available (from the
source). For the case of lossless filter components (le.,
perfect inductors and capacitors), this ratio is the frequency
response of the filter.

For example, a typical filter circuit which might be examined
by FILTER ANALYSIS is shown below. As you can see, there
is considerable flexability in dealing with serial/parallel
components as well as multiple stages.

The results of the analysis are available in several forms,
including a tabular display of the attenuation and reflection
coefficients, and a graphical display of the attenuation in
decibels .versus log-frequency (see below).

FILTER ANALYSIS is written in Applesoft BASIC but emulates
its own very friendly language The commands are T (text
for comments), E (enter data), R (run analysis), C (change
data), L (list circuit description), Q (quid and P (plot).

FILTER ANALYSIS is a very powerful tool for quickly and
easily testing filter designs.

FOURIER ANALYZER

(available for all computers)

FOURIER ANALYZER is a scientific program which can be
applied to examine the frequency spectrum characteristics
of defined duration signals, such as groups of pulses. The
user inputs a data set which is Fourier transformed into the
frequency space descriptors of amplitude and phase. The
amplitude and phase results are displayed in tabular form.
The input data and calculated results may also be plotted
at the user's option.

Shown below are plotting examples in which the input data
represented a square wave shifted off the origin. The
amplitude plot clearly shows the characteristic "sine"
function form. The phase plot shows the expected discrete
phase changes associated with the "sine" function super¬
posed on the linear phase change expected from the
Shifting Theorem.

The input data set is limited in extent only by the memory
size of the host computer, and is not restricted to equally
spaced values.

FOURIER ANALYZER is certainly a powerful and educational
tool for the engineer, scientist, student, or anyone involved
in cyclic phenomena (eg., music, stocks, etc).

Accompanying FOURIER ANALYZER is a 20 page manual.

TRANSFER FUNCTION ANALYZER

(available for all computers)

TRANSFER FUNCTION ANALYZER is a frequency spectrum
analysis package designed with the engineer in mind. It
applies the concept of the Fourier integral transform to an
input data set to provide a frequency domain representation
of the function approximated by that input data TFA is
based on OYNACOMPs popular FOURIER ANALYZER,
but includes special data handling features. It also presents
the results in conventional engineering terms (decibels,
log-frequency).

The user may save and recall both the input data file and
previously calculated results. Data files may be loaded
(from cassette, diskette, or disk), added to, deleted from,
and generally edited. As with FOURIER ANALYZER, the
input data may be plotted before the calculations are
started. The frequency domain results may also be plotted,
as well as saved (to be later recalled for new plots). In
addition, the analyses are easily separated with different
frequency parameters without re-entering the data

The transformed results are displayed in conventional
engineering form. The amplitude points returned are in
decibels (DB) relative to the peak value (0 DB). The phase
is in degrees. The frequency transform is calculated in
equal log-frequency intervals as is common practice in
Acoustical and Electronic Engineering

The frequency results may be optionally plotted When the
amplitude plot is performed, it is in decibel/log-frequency
format This permits easy identification of the characteristic
"roll-off' in frequency response. For example, a9 DB/octave
(eg, 10 log(F(W» straight line roll-off of a three pole filter
is immediately apparent from the plot

TFA was originally designed as part of a consulting assign¬
ment involving the analysis of amplifier transfer function. It
is, therefore, a program which has been tested in an actual

commercial application. In this particular case, the output
data corresponding to the real time response of an amplifier
to an input pulse ("delta function") was used directly as
input to TFA and the frequency amplitude results directly
gave the transfer function for the amplifier.

Whereas DYNACOMPs FOURIER ANALYZER is well suited
to the basic science and educational fields as well as many
engineering applications, TRANSFER FUNCTION
ANALYZER is a key tool for the electronics and acoustics
engineer involved in the analysis of limited duration
signals. Included in this package is a well written 20 page
manual.

24K).

HARMONIC ANALYZER

(available for all computers)

HARMONIC ANALYZER is the third in DYNACOMPs
series of Fourier transform software packages. Whereas
FOURIER ANALYZER and TRANSFER FUNCTION
ANALYZER (TFA) were designed with limited duration
signals in mind, HARMONIC ANALYZER is specific to
repetitive wave forms (cyclic processes).

All the data entry, storage, retrieval, and editing features of
TFA have been included, as well as the signal and transform
plotting functions. The Fourier integral has been replaced
with a Fast Fourier Transform (FFT) routine which is the
essence of the harmonic analysis. A cubic spline interpolation
procedure has been added so that the user may transform
irregularly spaced data Also, the data need not be entered
in temporal order; it is sorted before being transformed.

The spline interpolation and sorting features are unique to
HARMONIC ANALYZER and will be appreciated by those
familiar with other FFT programs which require the data to
be both in order and evenly spaced. The spline interpolation
scheme was in particular chosen over others to minimize
the unwanted interpolation oscillation (" ringing') associated
with abrupt signal changes, such as square wave steps.

The FFT employed is a base-2 algorithm; that is, the
number of data points must be an even power of 2. This
places a small restriction on the input data set, but
increases the speed of the transform calculation.

HARMONIC ANALYZER is a program which shoulcf be in
the software library of every scientist engineer, or
experimenter who deals with repeating waveforms.

A 16 page manual is included. Requires 16K of program
memory (Atari version requires 24 K).

DIGITAL FILTER

(available for all computers)

DIGITAL FILTER is a comprehensive data processing
program which permits the user to design his own filter
function or choose from a menu of filter forms. The filter
forms are subsequently converted into non-recursive
convolution coefficients which permit rapid data processing
In the explicit design mode, the shape of the frequency
transfer function is specified by directly entering points
along the desired filter curve. In the menu mode, ideal low
pass, high pass and bandpass filters may be approximated
to varying degrees according to the number of points used
in the calculation. These filters may optionally also be
smoothed with a Hanning function. In addition, multi¬
stage Butterworth filters may be selected. Features of
DIGITAL FILTER include plotting of the data before and
after filtering as well as display of the chosen filter
functions. Also included are convenient data storage,
retrieval, and editing procedures.

The format of the data storage is consistent with that used
by REGRESSION I, REGRESSION II, TRANSFER FUNCTION
ANALYZER, and HARMONIC ANALYZER. This permits the
user to selectively filter data before processing by any of
the above programs.

DIGITAL FILTER is extremely well documented with a 48
page manual which carefully describes the operation of
the program as well as the supporting theory. The manual is
sufficiently complete that it can be used in conjunction
with the software to teach many of the principles involved
in digital filtering

be to the engineering and science departments. The
documentation is short but good ... The theory upon
which the program is based is clearly presented with
several references. Annotated examples are given in the
manual and data files are provided on the program disk
so that the user can actually duplicate the examples.
Overall a good program that would be useful as a self¬
teaching tool for anyone having a moderate motivation
to become familiar with digital filters. For college
science and engineering collections."

MATH MASTER SERIES

THE MATH MASTER SERIES comes In several modules:

MATRIX MASTER BOOLEAN MASTER

POLY MASTER COMPLEX MATRIX MASTER

POLY ROOT MASTER EDIT MASTER

MATH MASTER EXECUTIVE
FAST FOURIER TRANSFORM MASTER
All but the EXECUTIVE are free-standing modules, that
is, you need nothing but that module and BASIC to
implement the enhancement However, if you want to
use two or more modules simultaneously, the MATH
MASTER EXECUTIVE is also required to coordinate the
modules.

Note: Modules are read in only when a different module
is called. Ten matrix calculations in a row result in only
one MATH MASTER module load.

Each module is described below in some detail. As you
will see, you can greatly enhance the capabilities of
your BASIC with MATH MASTER modules.

MATH MASTER EXECUTIVE

(Apple, IBM and TRS-80 only)

The MATH MASTER EXECUTIVE automatically loads in
MATH MASTER programs as they are needed. For
example, suppose a program contains these two
statements:

60 CMD MAT A = B+C

70 CMD POLY R =S+T

First, MATRIX MASTER would be automatically and
quickly loaded into RAM and executed to give the sum of
matrices B and C in matrix A. Then POLY MASTER would
be automatically loaded into RAM and executed to give
the sum of polynomial coefficient vectors S and T in
vector R. The only effort required on the part of the user is
that of making sure that POLY/EXC and MAT/EXC reside
on a disk in one of the disk drives.

Price: $19.95 Diskette

Note: 128K RAM (or more) needed for the 1BM version of
MATH MASTER EXECUTIVE.

MATRIX MASTER

(Apple, IBM, and TRS-80 only)

MATRIX MASTER greatly simplifies and speeds up those
very time-consuming matrix operations which are often
encountered. For example, a 20 by 20 matrix can be
inverted in only 15 seconds (IBM version; single
precision). That's fasti The typical BASIC command
would be:

100 CMD MAT A = B+C

The quotations supported are addition, subtraction,
multiplication, transportation, inversion, scalar opera¬
tions, identity matrix creation, and fast storage and
retrieval. Although available in single- and double¬
precision versions, double precision is recommended for
matrix inversion.

FAST FOURIER
TRANSFORM MASTER

(Apple, IBM, and TRS-80 only)

FFT MASTER is presently the most popular of the MATH
MASTER series because of the need for a truly fast FFT
and one that has the features this has. For speed, consider
the following: 26 seconds (IBM version) for a 1024-point
single-precision real transform!

Two versions of FFT MASTER are available:

• SINGLE PRECISION for “run of the mill" analysis.

• DOUBLE PRECISION for exacting analysis.

The size of the array processed is limited only by available
•RAM. All of the transforms are performed "in place". This
saves memory. And all of the transforms can be
performed with Hanning windowing. Also, inverse trans¬
forms can be computed.

Here are some examples of the command formats:

100 CMD FFT A REAL

The N elements in A(l) are taken to be real and the
complex transform is returned in A(l): A(0) and A(1) are
the real and imaginary parts of the first of the N/2 output
points.

200 CMD FFT A INVERSE

The inverse transform of the complex array A(l) is
returned.

300 CMD FFT A REAL HANNING

Modifiers can be compounded. Here the real array A(l) is
windowed before being transformed.

300 CMD FFT A MAG(B)

The magnitude of the transform of A(l) is returned in B(l).
400 CMD FFT A PHASE(C)

The phase (in radians) of the transform of A(l) is returned
in B(l).

There are also utilities for quickly storing and retrieving
data.

As usual with FFT algorithms, FFT MASTER is limited to 2 m
data points.

THE MATH MASTER SERIES

(Apple, IBM, TRS-80)

We learned a lesson from DYNACOMP's BASIC SCIEN¬
TIFIC SUBROUTINES (BSS) series: People want to ex¬
tend the math capabilities of their machines. With BSS
you can select any of a large number of subroutines
written in BASIC and append them on to your own
programs. Now a few of the more popular routines
have been converted to machine language and have
been included in BASIC as special statements. For
example:

100 CMD MAT A = INV(B)

is a statement in the MATRIX MASTER enhancement
of BASIC which calculates the inverse of matrix B and
puts it in matrix A. As you can see, the program state¬
ment is very simple and easy to use. Also, the calcu¬
lation is fast.

MATH MASTER SERIES

POLY ROOT MASTER

(Apple, IBM, and TRS-80 only)

POLY ROOT MASTER allows you to determine quickly
and easily the roots of polynomials using a simple
command structure:

100 CMD ROOT A = R(B) AND 1(C) USING(D)

when A is the polynomial array, B is the real root vector, C
is the imaginary root vector, and D is a dummy work array.
For example, B(0) and C(0) are the real and imaginary
parts of the first root found, etc Simple and fast

BOOLEAN MASTER

(Apple only)

BOOLEAN MASTER adds 23 new 8-bit and 16-bit logical
functions to Applesoft BASIC You can shift bit set bit
reset bit test complement XOR, OR, negate, PEEK/
POKE (16 bit). Most of these functions can be either 8-bit
or 16-bit Also, there is a base-conversion command
(base range: 2 to 36). A typical command line might look
like this:

100&BOOL (B=BSET(A,I))

In this case, the fifth bit in A is set and the result is
returned in B.

If you are involved in bit mapping or other bytewise
logical operations, you will find this machine-language
enhancement to Applesoft BASIC a huge time saver.
Requires 48 K.

Price: $29.95 Diskette

EDIT MASTER

(Apple only)

You do not need EDIT MASTER for the TRS-80 or the IBM;
they already have very nice program line editors. But the
line editor in the Apple is awful. EDIT MASTER solves this
problem. With EDIT MASTER you can easily insert,
delete, and find characters. You can zap sections of a line,
pack lines (remove unnecessary spaces), scroll through
text, move to the front or end of aline, etc In other words,
EDIT MASTER is what should have been included in
Applesoft. Further, EDIT MASTER is fully integrated with
the MATH MASTER series; it can be part of the automatic
EXEC library. In essence, it adds more commands to
Applesoft. Requires 48K.

Price: $19.95 Diskette_

COMPLEX MATRIX MASTER

(Apple, IBM, and TRS-80)

COMPLEX MATRIX MASTER is very similar to MATRIX
MASTER, but for complex (real plus imaginary) matrices.
The real and imaginary parts of the matrix A'(I,J) are
encoded into the BASIC matrix as follows:

Re A' (l,J) = A (l,2*J)

Im A' (IJ) = A (l,2*J+l)

You may perform all the operations available in MATRIX
MASTER.

Suggestion: If you deal only with real matrices, use
MATRIX MASTER only; it consumes one-half as much
memory and is slightly easier to use.

Price: $39.95 Diskette (Single Precision)

POLYMASTER

(Apple, IBM and TRS-80 only)

POLYMASTER allows polynomial operations to be
quickly and easily accomplished using symbolic state¬
ments like:

100 CMD POLY A = B+C

The operations available are 4*, —, *, /, greatest common
divisor, integral, evaluation, and setting one polynomial
equal to another. Also included is a fast disk storage and
retrieval utility.

ECM TURING MACHINE

(Apple only)

A Turing machine is the simplest operational model of
the format definition of computation. ECM TURING
MACHINE portrays this concept in a way meaningful to
students lacking an extensive background in comput¬
ability.

The Turing machine has only five instructions, but can
compute anything computable (within the constraints
of available memory). ECM TURING MACHINE is
composed of two parts. A set of state descriptions
provides the instructions and controls the action
performed under a given condition. A "tape" (a string
of symbols) supplies the conditions for the state
descriptions, and is the only input/output of the Turing
machine. In the ECM version, there are 400 state
descriptions.

ECM TURING MACHINE is not a programming lan¬
guage for developing applications software. There are
better languages for doing this (e.g., BASIC, PASCAL).
Rather, it is a fundamental teaching tool designed to
instill an understanding of computability and appre¬
ciation of the logic behind computing.

For use in high school or college-level computer
courses, or for personal instruction. Requires 48K and
one disk drive. Includes a 65-page tutorial manual.

_Price: $49.95 Diskette

STATE VARIABLES

(CP/M and IBM only)

STATE VARIABLES is designed to solve systems of ordi¬
nary differential equations (up to ten) which include a
forcing function. For example, a network of RLC elements
subjected to a varying input voltage can be easily ana¬
lyzed. You may choose five types of forcing functions: a
constant, ramp, step, sine wave, or user-defined function.
The program then solves the problem and both prints and
plots the resulting solutions (including derivatives).
STATE VARIABLES is a very nice tool. Requires 48K,
printer is optional. Price: j 29 . 95 0iskette

DIFFERENTIAL EQUATIONS

(CP/M and IBM only)

DIFFERENTIAL EQUATIONS is a series of programs
which yield numerical solutions to ordinary differential
equations given suitable initial conditions. Only two re¬
strictions are placed on the differential equation being
solved. First, it must be explicitly expressable in some
sequence of the standard BASIC mathematical opera¬
tors: +, —, *, /, EXP, LOG, or the trigonometric functions

SIN, COS, and ATN (or ATAN). Second, enough initial
conditions must be provided to make the solution
unique — that is, for an equation of order N, N simul¬
taneous (at the same value of the independent variable) -
initial conditions must be known. Several different
methods of solution can be chosen from, including Euler,
Improved Euler, and Runge-Kutta techniques. An op¬
tional extrapolation routine provides improved accuracy
for any data obtained. The results of any sol ution may also
be plotted if desired. Output to a line printer is also
supported.

BEWARE THE CHEAP DISKETTE!

During the past year, the prices of diskettes have
dropped remarkably. Also, In many cases, so has the
quality. It looks like several well known manufacturers
have lowered their costs (in an attempt to be competi¬
tive) by cutting corners in manufacturing.

For 574 " diskettes, we are currently selling only one
brand: Nashua. It is not unusual for DYNACOMP to run

1 0,000 Nashua diskettes through its duplication facilities
y and turn up only one bad diskette. Nashua diskettes are
not only good, but they have the smoothest surface (as
discussed in a BYTE Magazine product comparison), and,
as we have found, have the highest reliability of all brands
tested (and we have tested quite a few!).

Yes, you may be able to find cheaper diskettes, but they
are cheaper, not less expensive (in terms of what you get
for your money). DYNACOMP usually does not recom¬
mend one brand over another, but you should know that
our production group loves Nashua diskettes!

ANALOG

(CP/M only)

ANALOG simulates the operation of an analog computer
system on an 8080, 8085 or Z80 microprocessor.

Distinct advantages over an analog computer can be
provided by using the microcomputer for continuous
system simulation work. The output can be made directly „
available on hard copy. The configuration can be readily
modified and a hard-copy record of all configurations can
be maintained. The results are generally obtained more
rapidly and less expensively than on an analog computer.

In ANALOG, the normal analog computer patch panel is
simulated by specifying the interconnections between
the 32 types of computational blocks available in this
program. Through the use of the appropriate combi¬
nation of these blocks, the response of any time-
dependent system can be determined.

The program sorts the configuration blocks into a logical
order that is appropriate and therefore the sequence and
numbering of the blocks in the configuration is of no
significance. The program user may order and number his
(or her) blocks in any fashion he (or she) desires. The user
may select either the 2nd or 4th order Runge-Kutta
technique.

Some of the outstanding features of ANALOG are:

• Interactive control

• Dynamic configuration modification

• Dynamic initial condition and parameter
modification

• Large simulation capacity with 250 elements or
blocks

• Graphic and/or Printed numerical output

• Runge-Kutta integration

• Dynamic selection of 2 nd & 4th order integration

• Automatically scaled graphics

• Menu driven

• File output for use with other programs

• Configurations may be developed on line and
saved in a file

• 32 block types available

• Dynamic help level control

• 14 Primary commands

• Function generators with dynamic control

• Input in upper or lower case

t Low-resolution graphics output on any CRT or
printer

• Mnemonic commands

• Dynamic display of the Simulation Time

ANALOG is supplied with a detailed manual which
includes examples. It requires an 8080,8085 or Z80 CPU
with 64K of RAM, one disk drive, and a printer (very
useful) which will print 120 or more columns. MBASIC is
not required.

MATRIX 100

(IBM only)

Although MATRIX 100 is in many ways similar to
MATRIX MASTER, it contains some additional features
and capabilities which appeal to the more sophisticated
user.

MATRIX 100 adds new commands to BASIC (the syntax
is almost identical to MATRIX MASTER). These allow:

• Matrix multiplication, addition, inversion, deter¬
minant, etc.

• Solving of linear equations.

• Multiple regression.

• Obtaining LU, QR factors, and solving.

In addition, you can examine regression statistics,
numeric stability, etc. The package includes sample
code to interactively solve linear equations and find
eigenvalues (for real symmetric matrices).

MATRIX 100 is fast. It runs about 100 times faster than
BASIC. The 8087 version (MATRIX 100/8087) runs
more than 1000 times faster than BASIC.

MATRIX 100 requires IBM's BASICA (specifically), 128K
of RAM, and one drive. To use MATRIX 100, you must
be familiar with mathematical programming in BASIC.

REVIEWER'S COMMENTS

(Anthony Barcellos, PC Magazine, May 1985)

The 33-page MATRIX 100 user's manual is excellent
Beautifully typeset in multiple fonts for readability, it
describes each command clearly, explains any options
or parameters, and gives explicit examples.

The $80 price is extremely reasonable.

After returning my review copy of MATRIX 100, I ...
ordered a copy for myself.

MORE REVIEWER'S COMMENTS 1

In summary, the package is both very powerful and very
easy to use. I recommend MATRIX 100 to anyone doing
work in BASIC. __

BIQUAD FILTER DESIGN TUTORIAL

(Apple only)

BIQUAD FILTERS is another in the DYNACOMP
electrical engineering tutorial series, and the product
structure is the same: a two-part manual which
describes the theory (with many, examples) and
program operation, and a graphics-oriented software
package. .

BIQUAD FILTERS not only teaches by example, but also
allows the determination of the poles and zeroes
required to produce various filters including:

• Analog anti-aliasing.

• Digital low pass, high pass, and band stop.

You may design Butterworth and Chebyshev low
pass/high pass (up to 8 poles) and band pass (up to 4
poles) digital filters, and graphically observe both the
analog and digital responses.

To use BIQUAD FILTERS, you must be familiar with the
bilinear transform (an earlier tutorial in this series).

CURVE FIT UTILITY

(IBM only)

CURVE FIT UTILITY (CFU) fits curves to data. It
provides flexibility in selecting curve types, data
weighting factors, and data input/output devices and
formats. CFU can be run stand-alone or can be used in
conjunction with other software such as spread sheets,
data bases, plotting packages, or other scientific or
business applications software.

FEATURES

Data Input - Data for curve fitting can be input directly
from the keyboard or it can be loaded from a disk file. A
spreadsheet program, for example, can write data to
disk which in turn can be read by CFU.

Data Display and Edit - Once the data is entered from
the keyboard or disk, you have the ability to list and edit
that data. Points can be added, deleted, or modified'as
desired.

Curve Fitting - You can choose to fit to any of nine
general curve types, with variations allowed within each
type for a total repertoire of 32 mathematical functions.
The nine general curve types are: linear, logarithmic,
exponential, power, polynomial, constant to the x
power, parabolic, Gaussian with linear trend, and sine.
Two types of data weighting are also available.

Curve Extrapolation - Once the curve fit has been
established, the user can supply "x" values and the
program will calculate the corresponding fitted "y"
values.

Curve Output - The curve fit parameters plus a
calculated curve can be stored in a disk file. By this
means, curve fit results can be passed on to other
programs such as high resolution graphics plotters.

Graphing - The data and the curve can be graphed on
the CRT or the printer. This is a primitive character plot
intended only to let you Visualize the data and curves
generated by CFU. High resolution graphics is not used.

Statistics - The rms error and chi square are calculated.

CFU runs on any MS-DOS (or PC-DOS) machine with at
least 192K of RAM. A printer is useful but not
mandatory. All graphics are alphanumeric.

OMNI-FIT

(IBM only)

OMNI-FIT is a curve fitting package with features and
capabilities which place it midway between DYNA-
COMP's popular REGRESSION I/ll and PARAFIT II.

The purpose of OMNI-FIT is to greatly simplify the task
of fitting data to an equation form. OMNI-FIT provides
the most common curve forms as menu-selectable
options (linear regression, polynomial exact fit, poly¬
nomial least squares fit to order 8, exponential, power
curve, cubic spline between neighboring points).
OMNI-FIT can also fit data to forms defined by the user.

OMNI-FIT is menu driven and incorporates numerous
user-friendly features such as single-keystroke menu
selections, automatic datafile backup, automatic plot
dimensioning, several hardcopy options, logarithmic
and semi-logarithmic plots, etc. It will also integrate the
fitted data or a user-defined curve. The derivative of the
curve can be taken at any point and multiple roots of
any equation or curve fit can be calculated. Graphical
output supports both the IBM and the Hercules color
cards.

MAIN FEATURES:

• Fits data to a wide range of equation forms.

• Provides standard deviation of curve fits.

• Integrates over a definite interval.

• Approximates first derivatives.

• Solves for the root or roots.

• Plots data or curves in linear, semi-log, or log form.

• Interpolates between data points based on best
curve fit.

OMNI-FIT is not as fast or as "robust" as PARAFIT II, but
it can handle most of the curve fitting problems
commonly encountered. It also has exceptionally nice
data editing and plotting features.

MULTIPLE REGRESSION

(Commodore 64 only)

MINT computes integrals of any order, that is, single,
double, triple, ...n-tuple integrals, to an accuracy
specified by the user. This is accomplished by employ¬
ing an adaptable integration scheme.

The integration is performed using fourth degree
approximating polynomials, hence yielding more accu¬
rate results than using Simpson's rule. You may select
the names of the variables to be used and predefine any
recurrent constants.

The integrand and the limits may all be defined by
expressions with the same flexibility and capability as in
FUNCTIONS.

A printer is supported. Includes a 16-page manual.
Price: $19.95 Diskette

FUNCTIONS

(Commodore 64 only)

FUNCTIONS may. be used in a defined interval to find
the roots, maxima and minima, the integral, derivatives,
and to plot a graph of a function. The function may be
either an expression or a finite power series (polyr
nomial) read from a disk file. The expression may be up
to 1,000 characters long and is easily entered frbm the
keyboard. The power series may have up to 50 terms.
You may predefine any recurrent constants, and specify
the error bound for the results.

Integration is accomplished by the use of an adaptable
integration scheme. It is performed using a fourth
degree approximating polynomial, yielding more accu¬
rate results than using Simpson's rule.

For roots and maxima and minima, FUNCTIONS can
fully explore user-defined intervals to search for
multiple solutions. It can also quickly find single roots
starting with an initial guess. In addition, derivatives of
any order may be calculated at any point.

High-resolution screen displays are available. The axes
may be placed anywhere, and the window user-defined.

Besides the usual mathematical functions available in
BASIC, eight more have been added: two additional in¬
verse trigonometric, three hyperbolic, and three inverse
hyperbolic. These may all be used in the full (up to
1,000 characters) expression.

Includes a 26-page manual. A printer is supported.

LINEAR ALGEBRA

(Commodore 64 only)

LAL solves simultaneous linear equations, finds the
determinant or the inverse of a matrix, and computes
the product, the sum, or the difference between two
matrices. It also has the ability to find the real
eigenvalues. The corresponding eigenvectors are com¬
puted using the shifted inverse power algorithm. For
further efficiency, the matricies are first transformed
into their upper-Hessenberg form.

LAL also permits scalar multiplication, the shifting of the
diagonal elements, the transposition of a matrix, as well
as the creation of matricies of zeroes, of ones, identity
matrices, or general matrices.

The data for the computations may come from the
keyboard or from disk files. The result, if it is £ matrix,
may be filed to be used later for other operations.

Matrices may be easily reviewed, edited, and filed
before the operations take place.

A printer is supported. Includes a 39-page manual.

REGRESSION ANALYSIS II

(Commodore 64 only)

REG II performs bivariate or multivariate, linear or
nonlinear regression analysis. It fits a user-chosen curve
type to a given set of data points using the least-squares
method, determines the regression coefficients, as well
as the generalized correlation coefficient and the
standard error of estimate. You may select the names of
the variables to be used and predefine any recurrent
constants, as well as review and edit the constants,
functionals, and data.

Two types of disk files may be created or read: one with
the data and the curve used, the other with the data
only. These may be retrieved later to be expanded upon
or edited.

A high resolution plot of the resulting regression curve
and a scatter diagram are available. The axes may be
placed anywhere and the window either user-defined
or self-adjusting. The two plot modes enable you to
view ordinary plots or, for example, log-log plots.

The individual mathematical functions available are the
same as in FUNCTIONS. The length (1,000 characters)
of the fitting expression gives ample room, and very
complicated expressions, both linear and nonlinear
(with nonlinear cross terms, etc.) may be fitted. Data
values may be later interpolated/extrapolated.

LODE solves boundary value problems involving linear
ordinary differential equations of any order, with
variable coefficients. The boundary conditions may also
be equations involving the unknown function and its
derivatives, and the evaluation point may be different
for each one.

The differential equation and each boundary condition
may be an expression up to 1,000 characters long, and
are entered directly from the keyboard using an easy
operator syntax.

The solution produced is a continuous function in the
form of a finite power series valid in the entire defined
interval and expanded about a chosen center of
expansion. Up to 50 terms may be included in the
series. A high resolution screen plot of the solution is
available. The axes may be placed anywhere, and the
window user-defined.

The solution may be stored in a disk file which may be
later read by a suitable program (like FUNCTIONS) to
further study it to find its roots, maxima and minima,
derivatives, and integral.

The functions available for use in the equations are the
same as in FUNCTIONS.

MATH GRAPHICS

PC MATH PACKAGE

(Apple only)

PC MATH PACKAGE is a collection of routines that allow
you to use the Apple to do calculus operations. The
plotter portion will graph both normal and parametric (a
unique feature; you enter the equations for X(T] and
YlTl) equations. The program prompts you for the
equations, and you simply type them in. These
equations may be plotted in standard Cartesian
coordinates or polar coordinates. Also, one or both axes
may be logarithmic rather than linear. You have total
control over the scaling of the graph, or the program will
automatically scale for you if you wish. Functions may
be plotted on a blank screen, or on the axis or grid for
enhanced readability. Multiple functions may be plot¬
ted simultaneously, and five colors may be chosen to
help differentiate between each. You may also choose
to "fill" below curves. Also included is a labeling
program, with which each graph or set of graphs may be
labeled. Pictures created with the plotter may be saved
to disk for future use. All of the standard functions are
available, including SIN(X), COS(X), EXP(X),
ARCCOS(X), COSH(X), etc. <38 in all; more can be
added by the user). Also, the inverse, derivative, and
integral of the function can be calculated and displayed.
Included along with the plotter is a program to analyze a
function for min/max and roots.

PC MATH PACKAGE is aimed at people interested in
performing calculus on the computer. It is particularly
useful to high school or college instructors as a teaching
aid, and also to students interested in experimenting
with calculus on their own. The plotter segment is a
valuable aid for those wanting to graph sets of data
easily and quickly, either for school or business.

Requires a 48K Apple II+, lie, or lie with one drive.

If you're a student, teacher, mathematician, engineer or
scientist in search of mathematical analysis routines, this
package is for you. Elegantly written and user-oriented,
this group of four programs makes maximal use of Hl-
Resolution plotting capabilities to augment math rou¬
tines and display the results. The program contains a
master menu to run any one of the following programs:
Statistical Analysis: A general purpose menu-driven
statistics package that allows the user to analyze numeri¬
cal data bases. The program computes and displays:

a Simple Linear Regression Line* Mean
a SLR Equation Coefficient • Standard Deviation
a Frequency Distribution Plot a Data Points

Included are routines for disk data file I/O, editing and
printer output.

Numerical Analysis: This program will plot any two
variable equations that you can write using standard
Basic arithmetic functions. The program will plot the
equation, its integral, and its derivative. It will determine
and list roots, maxima or minima encountered and the
integral value over the plot range.

Matrix: This program allows you to solve for the inverse,
determinant and solution matrix for linear systems of up
to 54 equations in 54 unknowns. It uses standard Gauss
elimination with pivoting for maximum efficiency. Inclu¬
ded are standard data-base management routines for

PC GRAPHICS

(IBM only)

PC GRAPHICS is an integrated graphics package
designed for both engineering and educational appli¬
cations. With PC GRAPHICS you may graph XY and XYZ
coordinate equations, as well as parametric and polar
equations. Experiment with data while maintaining
control over scaling, position of the origin, interval, and
increment for the dependent variable(s), etc. You may
even determine relative maxima and minima, solutions
to polynomial equations, intersection points, etc.

It is easy to set up multi-line functions using a BASIC-
like syntax. Example:

IF X < 0 THEN Y = X A 2 ELSE Y = SIN(X)

In addition to being able to send a graph to a graphics
printer without distortion, you can save 9 screens on
each data diskette; three from the XY-coordinates
grapher and two from each of the other three systems.
The multiple screen saving capability is particularly
useful if you wish to prepare graphs in advance for a
later presentation.

Other features include:

• You can imbed up to three parameters in your
equations. These values can be varied as part of your
multi-line function, or from the keyboard.

• Plot colors can be changed between parameter
changes.

• Intersection points are displayed; you can zoom in
on them if desired.

• XY axis can be rotated.

• XYZ (3-D) plots can be rotated at will about the Z
axis (very useful!).

• An unlimited number of graphs can be overlayed on
the same coordinate system.

• Variable magnification (up to one million) centered
on any point

• Variable demagnification (up to one million).

• Up to 16 relative maxima/minima can be shown,
even if the region is not within the screen.

• Automatic decimal (ones, tens, etc) calibration of
axes.

• 3-D hidden line removal is selectable, upper/lower
surfaces in different colors, can be shown separately,
etc.

The 50-page manual also includes information on
advanced applications, such as how to graph discrete
sequences, recursively defined functions, functions in
the complex plane, etc. PC GRAPHICS is both powerful
and versatile, and can be used in a mathematics class as
well as in engineering applications requiring visual
representations of functions.

Requires 128K of RAM, color graphics. A printer is
supported.

THE SYNTEL MATH TOOLBOX

(IBM only)

The TOOLBOX is a powerful programmable calculator
that enables you to do sophisticated mathematical
calculations easily. You enter arithmetic statements as
you would normally write them and then, with a
keystroke, ask the TOOLBOX for the answer. The
TOOLBOX includes a complete set of built-in trig¬
onometric, logarithmic, and exponential functions. It
also has a powerful programmable feature. You can
define your own functions and then provide parameter
values for these functions for solution. You can save all
your computations on a disk file and load them back.

The GRAPH command is a flexible tool for creating
visual representations of mathematical functions. You
can create a variety of graphs.

Features:

• Character/Bit-map Graphs. Draws graphs in char¬
acter as well as bit-map mode.

• Tables. Generate numeric tables of functions, to the
desired precision. By using the table feature in
conjunction with the plotting capability, you have the
ability to do all kinds of scientific plotting.

• Graph Labelling. Enter labels, titles, and legends to
graphs. The TOOLBOX lets you write anywhere in the
graphics space with a full-screen editor.

• Automatic Scaling. Automatically choose optimal
numeric scales so that the graph fits the data. You can
also set scales manually to produce particular visual
effects.

• Graph Printing. Print out the graph immediately on
your C. ITOH or EPSON printer.

• Two basic statistical functions, linear regression and
standard deviation. The input data long with the linear
regression line can be plotted.

IBM OWNERS,

BUY THIS IF NOTHING ELSE!

(IBM only)

DYNACOMP is distributing two exciting MS-DOS
utilities which are really super and which we strongly
recommend.

The first, MEDIA MASTER, allows you to read a huge
number of different CP/M and MS-DOS format disk¬
ettes (e.g., Osborne, Kaypro, Xerox, Morrow, and soon).
The second, ZP/EM, allows you to run almost all CP/M
.COM programs that do not do anything special with the
hardware. For example, MBASIC.COM (Microsoft
BASIC) can be moved from a CP/M diskette to your MS-
DOS diskette using MEDIA MASTER, and then run using
ZP/EM. This opens up a whole new realm of CP/M
software to MS DOS computers!

MEDIA MASTER and ZP/EM are described elsewhere in
this catalog. You may purchase them as a collection for
$59.95 (under the name of MEDIA MASTER PLUS),
which is an amazingly low price for a product which
does so much.

Examples: DYNACOMP's HEAT LOSS, REFERENCE,
MONEY, KEEP TRACK OF IT, and ANALOG programs
come on CP/M diskettes (e.g., KAYPRO II). Using
MEDIA MASTER PLUS you can run these on your IBM!

BASIC SCIENTIFIC SUBROUTINES BASIC SCIENTIFIC SUBROUTINES

BASIC SCIENTIFIC SUBROUTINES

VOLUME I

(available for all computers)

BASIC SCIENTIFIC SUBROUTINES. VOLUME I by
F. Ruckdeschel (published by BYTE/McGraw-Hill; see the
January 1981 Issue of BYTE Magazine, page 173) is the first
in a series of books designed to provide microcomputer
users with scientific subroutines written in BASIC. These
subroutines have been designed to facilitate the application
of microcomputers to scientific tasks which have previously
been largely in the domain of the large timeshare mainframe
computers.

Through arrangements with the author and BYTE/McGraw-
Hill, DYNACOMP has become the exclusive distributor of
three software packages keyed to the above text Each
package includes programs organized by chapter and
accessed/demonstrated by a special menu program written
especially for DYNACOMP. Unlike other software packages
commercially available which are keyed to texts, you do
not have to search the tape (diskette or disk) to load a
particular program. They are all loaded in one step and are
called according to the menu selection. This makes life
much easier for the user.

Because of the total length of the software listed in the text
(greater than 33 kilobytes), three collections have been
organized. Each collection will run in 16K of program
memory space (Atari requires 32-48 K).

Collection #1:

Chapter 2 - Alphanumeric Data Plotting

• Equally Spaced Data

• Arbitrarily Spaced Data

Chapter 3 - Complex Variables

• Polar Coordinate Conversion

• Addition, Subtraction, Multiplication,
Division

• Powers and Roots

• Spherical Coordinate Conversion

Collection ;

Chapter 4 - Vector and Matrix Operations

• N-vector Addition, Subtraction,
Multiplication (dot and cross products)

• N-vector Lengths

• Angies Between Vectors

• Matrix Addition, Subtraction, Multi¬
plication, Transposition, etc.

• Row Operations

• Cofactors, Determinants

• Inversion

• Eigenvalues

• Exponentiation

Collection #3:

Chapter 5 - Random Number Generators

• Uniform, Normal, Poisson, Binomial

• Exponential, Fermi, Cauchy, Gamma
Beta

• Weibull

Chapter 6 - Series Approximations

• Sine, Cosine, Arctangent

• Natural, Basel 0 Exponent and
Logarithm

Price. $16.95 per collection (Cassette)

$20.95 per collection (Diskette)

$23.45 per collection (8" Disk)

Accompanying each collection is documentation which
describes how to use the associated menu program.
Detailed descriptions of the the programs, input/output
parameters, and the algorithms employed in the
subroutines are to be found in the McGraw-Hill text
BASIC Scientific Subroutines, Volume I (316 pages)
which DYNACOMP also distributes ($29.95 plus $2.00
extra for postage and handling). We strongly re¬
commend this book. The three collections may be
purchased for a combined price of $44.95 (3 cassettes),
$53.95 (3 diskettes) or $59.95 (3 IBM 3740 format
disks).

VOLUME 3, CHAPTER II

BASIC SORTING SUBROUTINES

(Available for all computers except Atari)

There have been so many requests for the third volume of
the BASIC SCIENTIFIC SUBROUTINES series that the
author has decided to supply the chapters and sections
as they are finalized. The entire book has been written,
but each chapter is being reworked to ensure compati¬
bility with Volumes 1 and 2, as well as with the other
Chapters in Volume 3.

Volume 3 is basically a text dealing with statistical
subroutines, including data handling The second
chapter is concerned with numeric and alphanumeric
("alphabetical") sorting This topic was chosen for an
early chapter because data usually has to be ranked,
ordered or separated before any quantitative analysis can
ensue.

Seven (actually, fourteen; seven for numeric arrays;
seven for alphanumeric arrays) sorting routines are
discussed:

1. The bubble sort

2. The insertion sort

3. The Shell sort

4. The Shell-Metzner sort

5. The Butterfly-Hart sort

6. The heap sort

7. The quick sort

Each has advantages and disadvantages in terms of speed
under certain sorting conditions, code length, array
memory requirements, and equal element exchanges (a
very important property which is usually overlooked).

Also included in this chapter is a program for accurately
calculating moments (e.g mean, variance).

The subroutines are presented in the same REMarked
format as is the pattern in the other volumes. There are
demonstration programs for showing how they operate,
timing comparisons, input/output descriptions, variables
list, etc In other words, these programs are fully
commented and documented in the same way which has
made Volumes 1 and 2 so popular.

The package is composed of the disk(ette) containing the
subroutines and demonstration programs, and a preprint
of Volume 3, Chapter II (over 160 pages). ^

DIGITAL'IMAGE PROCESSING

DIGITAL IMAGE PROCESSING

(Apple Only)

DIGITAL IMAGE PROCESSING (DIP) is a must for any
scientist, engineer, student, photographer, or experi¬
menter interested in the digital representation of images.
This two-diskette package allows you to digitally manipu¬
late images (15 samples are supplied, including pictures
of Lincoln, Kirchoff, and Saturn) to remove interference,
noise, improve contrast, sharpen, and generally filter
images.

The manual is broken into two main sections. The first
describes the theory associated with digital filtering,
including histogram correction. The second half of the
manual deals with the HI-RES graphics examples and
routines which demonstrate the various ways in which an
image can be analyzed and altered.

DIP is HI-RES graphics and menu-orienteck Images (e.g.
before and after) can be displayed on a standard TV
screen or an oscilloscope. (Optional: The schematic for a
simple oscilloscope interface to fit in Slot #3 is given. It
uses three Analog Devices AD558 D/A converters). All
images can be stored and recalled individually for later
viewing.

The experiment menu includes processing examples
(you run them with your own parameters) for over-
or under-exposure (you will see how effective histogram
correction is for this!), noise, interference, double
exposure (you are given two different double-exposure
pictures to try to rescue) and poor contrast.

Each image may be manipulated in the following ways:

1 . Gamma correction (you choose the gamma).

2. Inversion (good for making slides).

3. Histogram correction (very powerful).

4. User-supplied non-linear contrast correction (you
supply the table look-up).

5. Digital filtered (you supply the filter function).

The fifth mode has several alternatives. You may filter in
the X, Y, or X/Y directions using moving average filtering
and combined thresholding and gradient enhancement
("unsharp masking" in photography). You may also
specify the filter in terms of poles and zeroes on the
transfer function (see also the EDUCATION section
under Z-TRANSFORM TUTORIAL, DIGITAL FILTER
DESIGN TUTORIAL, and BILINEAR TRANSFORM
TUTORIAL).

The manual concludes with a list of experiments to try in
order to get a "feel" for the utility of the many tools at
your disposal. Learn by doing.

Requires 48 K, one disk drive. Oscilloscope optional
(requires interface).

DIGITAL IMAGE PROCESSING ADAM OSBORNE COLLECTION ADAM OSBORNE COLLECTION

DIGITAL IMAGE PROCESSING II

(Apple Only)

DIGITAL IMAGE PROCESSING II (DIPII) is a follow-up to
the first package, DIP. It provides a means for converting
57344-pixel, bit-mapped images into 8192- and 2048-
pixel seven-level digital images. The converted image can
be displayed on the screen with a representation of the
video signal shown as an insert, or sent to an oscilloscope
(see DIP description). The diskette includes four HIRES
pictures on diskette.

DIGITAL IMAGE PROCESSING III

(Apple only)

(Includes assembled parts for a low-cost image scanner
and SCAN-A-PICTURE.)

DIGITAL IMAGE PROCESSING III (DIP III) is for those
who have graduated from DIP and DIP II and would like
to go further in image processing. In many ways, DIP III
ties together ideas from the various other engineering
tutorials (see EDUCATION-ENGINEERING section)
involving transforms and digital filtering. With DIP II, you
can get hands-on experience in the following areas:

• Gamma correction

• Histogram correction

• Look-up table correction

• Image smoothing, differentiation

• Template matching

• Image scanning

Also, you may repeatedly zoom in on an image; segment
it; invert it; create mosaics; graphically see the gray-scale
correction; convert 2K-pixel X 8 -level "halftone" images
to 8 K-pixel X 1 (bit mapped) images; sharpen; smooth
(5,9 point); threshold; and much more. Output may be
directed to either the TV screen or to an oscilloscope (see
DIP for a discussion of this feature).

DIP III comes with many images on disk to serve as
examples as well as image data for processing. In addi¬
tion, you may scan your own images (transparencies) and
process them. You may do this with a simple photo¬
resistor/transistor sensor device which connects to the
Apple through the paddle socket. DYNACOMP supplies
all of the parts necessary (comes assembled and tested),
a transparency for experimentation, and operating in¬
structions. With this device and the software included in
DIP III (SCAN-A-PICTURE), you may "capture" your own
2048-pixel X 8 -bit images, histogram correct, invert, etc.
DIP III comes complete with a 42-page main manual
(containing both theory and program instructions, an
assembled and tested photoresistor/transistor sensor
system, including socket and an experimenter's manual.

Requires 48K, and one disk drive. An oscilloscope is
optional (not necessary). Experience level necessary:
Moderate. Familiarity with DIP and DIP II is suggested.
Using DIP III is easy, but be prepared to experiment with
light levels, sensor positioning, etc.

THE

ADAM OSBORNE SOFTWARE
COLLECTION

(Available for all comupters except Atari)

Here are four collections of programs keyed to the text
SOME COMMON BASIC PROGRAMS published by
Adam Osborne,(book written by Poole and Borchers).
These collections received 10 (out of 10) ratings in our
North Star Software Exchange listing. They have been
translated to other machines covered by DYNACOMP
and are an absolutely excellent bargain.

The DYNACOMP versions come with a master menu
which allows you to easily choose the program desired,
execute it, and return to the menu. The DYNACOMP
versions have also been significantly improved and
corrected. The programs are generally self-prompting.
Although the documentation from DYNACOMP is suf¬
ficient for most applications, it is suggested that you
obtain the associated Osborne book. This book is so
popular that most computer stores carry it, or you may
order directly from Osborne/McGraw-Hill.

ATARI XL TRANSLATOR

(Atari XL only)

The new Atari XL series of computers has certainly
created a good deal of excitement. It has also generated
quite a bit of confusion!

Almost all of DYNACOMP's software for the "old" Atari
will run on the new XL's. The only ones that have difficulty
are just a few of those which use the disk for data storage
and retrieval. The typical problem is as follows: after
some time the program stops with a 162 error (disk full).
However, when you look at the directory, there are 40 to
50 bl ocks free! Ver y few people are getting this prrnr ,

Atari has acknowledged problems with XL machines and,
if you contact their Customer Service department, you
can obtain a diskette which will allow you to boot your
system so that it can run "standard" Atari software. If you
have trouble contacting them or want fast service, you
may get this TRANSLATOR diskette from DYNACOMP.

Price: $5.00 Diskette

ASTRONOMY

CELESTIAL BASIC

(Apple, C-64, and IBM only)

Ever wished you had a planetarium at home? Ever
wanted to check the positions of the planets or Jupiter's
satellites, or time in the past or future when you did not
have an almanac for that time? Or wanted quick access
to some data about a planet or one of its satellites?

Eric Burgess, F.R.A.S. has developed a series of programs
to answer these needs and has also written a book to
accompany them, called Celestial Basic. We can best
describe the quality of the program by quoting Arthur C.
Clark (author of 2001: A Space Oyssey): "I have run
them [the Celestial Basic programs] on my Apple II and
am overawed by the work and skill that must have gone
into them.”

Ascent to Orbit published by
John Wiley and Sons

So much for the praise; now for the contents—

Moon and Planet Programs (Disk #1)

• Right Ascension and Declination - provides the
approximate right ascension and declination of the
moon for any date and time.

• Umbral Eclipses - for a start date of any year, this
program tells you when the next umbral eclipse of the
moon occurs, gives the magnitude of the eclipse, the
local time of mid-eclipse, and the rise and set times of
the moon for the day of the eclipse.

• Dates and Times of Lunar Phases - provides a table
of lunar phases for any month with the choice of local or
universal time for the phase.

• Right Ascension and Declination of the Planets - is
divided into three parts. The first gives the right
ascension and declination based on the 1960 epoch
and using the equation of the center. The second gives
more accurate right ascension and declination based on
the 1980 epoch and uses Kepler's equation. The third
gives hard-copy printout of the 1980 epoch data. Each
also provides angular distance from the sun and
distance in astronomical units from the Earth.

• Planets/Sun/Moon Finder - This program helps you
locate the planets, sun, and moon relative to the stars
for any date. The program calculates the position of the
object and selects a star map for the appropriate part of
the sky, shows the constellations, and plots the chosen
planet (or the sun or moon). It also plots other planets
in the same region of the sky. You may plot a series of
intervals to show the motion of the planet across the
star field.

• Planets/Sun/Moon Rise and Set Times - provides
times when the planets, sun, and moon rise, transit, and
set for any location on Earth, for any date.

• Mars Oppositions - This program offers two alterna¬
tives: The first finds the next opposition of Mars. The
program asks for a start year and month, displays a plot
of sun. Earth and Mars seen from above the solar
system, counts off month by month and in smaller time
intervals as opposition approaches, until the date of
opposition, and then provides details such as angular
size, constellation Mars is in, distance from Earth, and so
on. The second alternative provides observational data
about Mars for any date.

• Mercury and Venus - has three sections: The* first
tells you when the next eastern or western elongation of
either Mercury or Venus occurs after a selected date,
and provides information about the planet selected.
The secbnd shows graphically how Mercury and Venus
swing from side to side of the sun. The third is used to
find out when it is best to observe Mercury and Venus
at any date and for any locality by indicating the rise
times before and after the sun.

• Jupiter's Satellite Configurations - For any date,
location, and time, this program provides data on the
configuration of the Galilean satellites of Jupiter and
makes a graphic display of the configuration.

• Worldwide Horizon Piots - An advanced graphics
program which allows you to display the night (or day)
sky on the monitor of your computer for any time and
date and any location on Earth. In addition, the program
displays Halley's comet for the 1910 and 1986
apparitions for times when it is expected to be visible in
amateur telescopes. The tail is sized and oriented as
expected. A planetarium-type horizon silhouette is
displayed on each skyplot. You can select north, south,
east, or west horizons, each of which overlaps those on
either side and covers 180 degrees of azimuth. This is
the most advanced and realistic skyplot program
available today and it is updated to 1980 coordinates.

Time and Tutorial Programs (Disk #2)

• Sidereal and Mean Time Conversion

• Julian Day from Calendar Date

• Updating Star Coordinates - provides right ascension
and declination for any epoch given the right ascension
and declination at another epoch.

• Transists of Pole Star - provides the time for any date
when Polaris transits the meridian and is at eastern and
western elongation.

• Astronomical Conversions - provides rapid conver¬
sions of astronomical measurements including: light
years, parsecs, astronomical units, telescope resolving
power, and metric units.

• Dates of Meteor Showers - provides details of
annual meteor showers for any calendar month and
shows a graphic star chart for you to identify the point
from which the meteors appear to radiate (the radiant).

• Solar System Data - a long program, loaded with
information about the solar system, its planets, and their

• culmination of 85 constellations (point at which they
reach highest point above horizon)

• miscellaneous events (such as oppositions of Vesta,
the largest asteroid)

For weekend astronomers, all dates include the day of the
week. The calendar's layout shows at a glance if the moon
will be favorable for night viewing.

STAR CAL II also provides a real-time astronomical clock,
keeping time in the following 6 standards:

• local standard

• local daylight

• local civil

• local mean siderial

HALLEY'S COMET LOCATOR

(IBM only)

With HALLEY'S COMET LOCATOR you will be able to
find this famous comet quickly and easily. You simply
type in your approximate latitude and the date on which
you wish to view the comet. The program will display a
star map (which can be. printed out) showing exactly
where the comet will be, the direction you should face,
and how far up in the sky you must look to see it. Also
provided are helpful hints on observing and information
on how the comet should appear on the dates you select.
A complete manual tells how to install, run, and use the
program. It also contains a special section on how best to
view the comet — how to find a good location to observe
from, what kind of optical aid is best, and general
information on finding your way around the night sky.

SPACE BASE STAR ATLAS

(Atari only)

SPACE BASE is an electronic realization of the traditional
sky atlas and catalogue. By means of a large scrolling star
mural with a cursor window, you can move your joystick
to select celestial objects and gain instant access to a
database containing descriptive, positional, and
physical information. If you already use conventional
sky atlases, you will find the ability to "pick-off” objects
for detailed study will seem more like a video game
than library research. The computer database is
accurate and up-to-date, and you get the information
fast!

Educators will find SPACE BASE informative and
attractive for teaching in the classroom. It can be used
in grade schools for descriptive instruction, much as you
would narrate a planetarium show with a flash-light
"pointer”. Advanced graphics features, such as the
multi-color Hertzsprung-Russell diagram, let instructors
introduce the elementary concepts of astrophysics in a
fascinating new manner.

If you are a new student of astronomy, you will find an
enjoyable means of developing your new mental
astronomical database. Using SPACE BASE, you will see
the great diversity of color, temperature, and size
among the brightest stars. You will also learn many of
their names. As you move through the mural, you can
explore many "deep-sky" objects.

SPACE BASE is easy to use — simply autoboot the
disk, move about with your joystick, and select objects in
the cursor window by pressing the trigger.

TOOLWORKS™

C/80 3.1

(CP/M only)

TOOLWORKS C/80 compiler is both a professional pro¬
gramming tool and a great way to get started with this
popular language. It supports full C structures, pointers
and arrays, all storage classes, static data initialization,
and in-line assembler. TOOLWORKS compiles all C
arithmetic and logical operators, and all control state¬
ments, including WHILE, IF-THEN-ELSE, SWITCH-CASE,
and GOTO. The only language features not supported are
TYPEDEF, arguments to line macros, nested blocks,
#LINE, bit fields, and double-data type. Float and long-
data types are available with optional MATHPAK.

TOOLWORKS includes a source for sample utility pro¬
grams, and an expanded C library of over 45 functions
providing random sequential and formatted input and
output, dynamic storage allocation, UNIX-style I/O re¬
direction and command-line wild card expansion, and
selectable program trace or execution time profile by
subroutine.

TOOLWORKS C/80 generates 8080 assembler code for
the AS absolute assembler (included), or ROMable code
for Macro-80 or RMAC. Library is supplied in assembler
source and REL formats plus commented C source for
system dependent routines. The C/80 version 2.0 was
ranked highest in execution speed and efficiency among
eight 8080 C compilers in the January, 1983 Byte
benchmark; C/80 3.1 is even better!

The 48-page manual includes a language summary and
bibliography of C references, and complements the
language reference manual, Kernighan and Ritchie's The
C Programming Language (not included). In published
reviews (see list below) TOOLWORKS C/80 consistently
scores at or near the top in code efficiency, completeness
of implementation, and compilation and execution time,
even when compared with compilers costing many times
as much. Many software products including LISP/80,
MYCALC, and C/80 itself, are written in C/80. We feel it is
the best value available in a CP/M C compiler, and are
proud to make an excellent, afordable C implementation
available to both beginners and serious software devel¬
opers.

EBASIC WITH STARBASE 3.2

(CP/M only)

What is EBASIC? EBASIC is a BASIC programming
language which has most of the standard features of
Microsoft BASIC, as well as some other capabilities
which many will find interesting. In fact, EBASIC is
very similar to CBASIC (available from Software
Systems), except EBASIC costs only a fraction of the
price. The operational differences are that EBASIC
has no PEEK/POKE, PRINT USING or CALL facilities.
It does have

The advantages which EBASIC has over Microsoft
BASIC are:

1) Line numbers are not necessary except for
GOTO/COSUB transfers.

2) "Procedures" can be included in the program
at the "compile" stage (good for structured
programming).

3) The precision is automatically 14 digits.

4) The syntax of the entire program is checked
during the compile step.

5) EBASIC run-time programs tend to be much
smaller in memory usage.

6) EBASIC is much less expensive.

EBASIC is easy to operate. We sometimes use it at
DYNACOMP instead of Microsoft BASIC. A con¬
densed manual is supplied with the diskette/disk.
Also, a copy of STARBASE 3.2 (a very popular
DYNACOMP program) is included on the diskette/
disk so that you may examine proper EBASIC syntax.
In addition, we recommend you obtain the CBASIC
manual published by Osborne/McGraw-Hill (avail¬
able through your local computer store). Runs on
8080 and Z80 CP/M systems. Requires 24K. A
knowledge of the use of CP/M's ED.COM text editor
(or some other) is assumed.

C/NIX

(CP/M only)

C/NIX is a package which adds UNIX-like features to
your CP/M system. The main features are:

• Hierarchial Directories

• Input/Output Redirection and Pipes

• Selectable Paging of Terminal Output

• UNIX-like Command Files

• On-line Documentation

• UNIX-like Commands and Utilities

• Search Path (avoids multiple copies of commands
and files)

C/NIX runs in conjunction with your existing 8-bit CP/M
2.X system, and maintains complete compatibility with
existing hardware, programs, and data.

The C/NIX system includes a UNIX-like shell, a small
BDOS interface module, and a set of utility programs.

C/NIX is designed for computer systems with substan¬
tial disk capacity. It is useful on high-capacity floppy
disk systems, but is at its best on hard disk systems. It
requires at least 42 K of disk space for the minimum
system. The set (cmnd) and grep (cmnd) utilities
require another 14K. If the on-line help feature is to be
installed, about another 114K is required on the system
disk or another disk.

When running, C/NIX occupies only 2.3 bytes of RAM,
reducing the space available to user programs (or TPA)
by that amount.

C/NIX was written in C, using the C/80 compiler from
The Software Toolworks. It includes a 58-page manual.

XPL, A NON-TRADITIONAL
ASSEMBLY LANGUAGE

(8080 CP/M and IBM only)

What is XPL? It is a combination of programming
language concepts. It is an assembly language that looks
and feels like a high-level language. But, like other
assembly languages, it lets the programmer get at the
deepest levels of the machine. Traditionally, assembly
language programs have been difficult to write, read,
and support, they are generally cryptic. However, XPL
provides the same kind of block structure as high-level
languages.

XPL is an excellent systems-programming language for
any job involving data structures, byte manipulation, or
tasks that require little computation, but lots of logic.

XPL is easier to remember, easier to write, easier to read,
and easier to maintain than "standard" assemblers.

For example, compare some XPL statements to their
traditional equivalents:

A=L MOV A,L MOV AL,BL

A=$HL MOV A,M MOV AL,[BXJ

A=5 LDI 5 MOV AL,5

A=$WORD LDA WORD MOV AL,lWORD]

A—A—1 DCR A DEC AL

A=A+5 ADI 5 ADD AL,5

A=^A CMA NOT AL

AF=~0 XRA A XOR AL,AL

There is also a special syntax for block-structured code.
Examples are DO...LOOP, IF...ELSE, NEXT, EXIT,
AGAIN, WHILE, UNTIL, GOTO, CALL, RETURN, and
CASE. Data declarations can be local or global.

Program libraries are also supported.

XPL consists of a 65-page manual and a disk containing
four programs to assemble, link, cross reference, and
print These programs come in two versions. One
version runs on CP/M, the other runs on PC-DOS/MS-
DOS. Both versions are produced from identical XPL
source code. XPL implements the complete 8-bit
instruction set and a compatible subset of 16-bit
instructions. Using both versions together creates a
cross-assembler (PC-DOS/MS-DOS to CP/M dt vice
versa).

The bottom line is that XPL is an easy-to-use assembly
language which creates fast code and is compatible with
both 8080/Z80 CP/M and PC-DOS/MS-DOS 8088
systems.

EOI-MATE GRAPHICS ANIMATOR

(Apple Pascal only)

EDI-MATE is a full-color high resolution graphics editor.
With EDI-MATE, entire screen images may be saved to
or retrieved from disk, or individual images may be
saved to or retrieved from a memory buffer. Up to 143
images of any size, from one bit up (limited only by
memory capacity: 2.5K to 4.5K), may be saved to the
memory buffer. These stored images, in combination,
allow you to form more complex images. You may work
on the entire Hi-Res screen or, for more detailed work,
any portion of the screen may be expanded three times.
You can flip any picture horizontally or vertically and
use any image as a pattern to fill an enclosed area — or
as a brush for "painting" screen areas.

Images may be combined into animation sequences by
the mini-animator. This animator allows creation of up
to 114 sequences with a sequence consisting of any
combination of individual picture placements and
previously defined sequences. Sequences may also be
looped for a specified number of times or until a key or
button is pressed. Entire buffers of images and
animation sequences may be saved to disk for later use.

Also included is a library of assembly-language pro¬
cedures that may be used in Pascal programs to display
images. Two sample programs are provided with heavily
commented source code as examples of how to load
and use picture files that have been made by EDI-
MATE.

Other Features:

• Easy to use. All commands are available as menu
choices.

• Supports a variety of input devices including
joystick, paddles, and the Koala Pad®. Commands may
also be input via the Apple keyboard.

• Compatible with Apple Pascal and TURTLE-

• Library of fast assembly language procedures may be
used alone or with TURTLECRAPHICS.

• Includes CHASE, a custom character set editor
(available separately for $15.00).

• Comes with a 65-page manual which carefully
describes all functions.

Requires Apple Pascal 1.1 or 1.2, at least 64 K of RAM,
and one disk drive. Optionally, a joystick, paddles, or
any other input device that plugs into the Apple "game
I/O" socket may be used. A printer is supported, but not

Typical uses include foreign-language alphabet creation
(e.g, Hebrew, Japanese) and icon creation (e.g., space
ships) for games.

MULTI-CHAR works very much like a text editor. You
may load, save, and modify character sets in a very fluid
manner. Characters can be individually copied from one
set to another, flipped, inverted, twisted, etc.

The DRAW option includes a wide range of graphics
capabilities to construct drawings: pre-drawn symbols
which can be modified, free-form lines, circles, arcs, arc
rotation, ovals, painting areas of the screen with solid
color, color palette changes, and picture merging.
Pictures can be saved in the gallery and recalled for later
modification.

The BROWSE option shows a floor plan of the gallery,
with a stick-person that can be "walked" around. When
the stick-person approaches a picture on one of the
walls, the work of art can be called up on the screen.
Pictures can be printed on a graphics printer with the
PrtSc (print screen) key.

The capacity of a gallery is 32 pictures. Picture file
handling is managed entirely by the computer so that an
understanding of disk files is not necessary.

THE ART GALLERY is exceptionally easy to operate. It is
entirely menu-driven, and prompts are provided
throughout the drawing process. There are no program
function keys or commands to learn. This simplicity
makes THE ART GALLERY especially suitable for
youngsters, as well as enjoyable entertainment for
adults.

THE ART GALLERY requires a graphics card and monitor,

colors and 3 different foregrorind colors on 2 separate
palettes to produce pictures that may be saved on disk.
There are no complicated commands to learn or special
devices needed. Anybody can start using COMPUTER
CANVAS within minutes.

The function keys help you to easily create circles,
boxes, diagonal and straight lines, paint in entire areas in
colors, alter background, foreground, and pailette
colors, create detailed patterns, and draw freehand on
the screen using directional keys.

You can repeatedly update and add to existing pictures
in addition to starting from a blank "canvas". Also, the
pictures are stored on disk in a standard format, which
allows them to be used by other computer programs.
This makes COMPUTER CANVAS a valuable tool for
those who want to add full color pictures to their
programs and need an easy, quick way to create these
pictures. You can also combine standard text with your
full color pictures, create pictures and label them, or
design charts and graphs and add titles, headings, and
explanations.

All pictures created with COMPUTER CANVAS can be
printed with DOS's Graphics command. The printed
images are detailed reproductions produced in multiple
shading to highlight the variety of colors on screen.

Requires 128K of RAM, color graphics card, and one
disk drive.

CREATOR and CREATOR II both allow the creation of
Osborne graphic displays-the display being the visible
52 X 24-character screen of the Osborne. With these
programs you can draw graphic characters, pictures, and
diagrams on the screen and then save the graphic dis¬
plays to disk. Once saved, they can be recalled from disk
and, if you have an Epson MX80 printer (expanded with
the Graf-Trax option), they can even be printed.

Drawing on the screen with CREATOR and CREATOR II is
much like editing a screen-sized document with Word¬
Star.

CREATOR is the predecessor of CREATOR II, and is less
powerful than the latter. However, DYNACOMP in¬

program in BASIC you may even modify parts of the
program. CREATOR II is in machine language, which
allows it to run much faster than CREATOR.

CREATOR and CREATOR II can be used for diagrams,
pictures, floor plans, artistic creations and the like. They
are simple enough to be used by children. CREATOR is
especially good in this regard.

CAT-GRAPHIX

(Apple only)

DYNACOMP is always on the lookout for high quality
software produced by outside authors. Usually we avoid
considering public-domain software because, quite
frankly, it is either poorly written, trivial, or very specific to
one person's needs. However, we occasionally en¬
counter a piece of public-domain software which we
think is good and should be more readilyavailable to the
public. What do we get from distributing this material?
Certainly not much in profit (we only cover costs).
However, maybe you will keep us in mind when thinking
about buying quality software at good prices.

CAT-GRAPHIX is a collection of programs and sub¬
routines for generating low- and high-resolution graphics
on the Apple. The subroutines are fast since they are
written in machine language. The support programs for
generating the tables and images are in Applesoft, with
calls to the machine-language programs. Included are
routines for rotating and scaling images, as well as for
scrolling.

This is an experimenter's and programmer's package.
Although there is accompanying documentation, you
really have to look at how things are done by examining
the demonstration programs (there are 20 of them!)

To make it easier for you to use this package, DYNA¬
COMP provides 35 pages of instructions and programs.
However, be forewarned that you will have to reed,
experiment, and think!

MAPIT

(IBM and CP/M-86 only)

MAPIT is a program for the creation of maps. The intent
is to make mapping available to anyone with a micro¬
computer. A great amount of work has gone into making
the program easy to learn and powerful to use. Many
people will consider using this program fun, but it is
meant for serious pursuits.

The uses of MAPIT are many. Some examples are
population density by area, relative concentration of
minerals, pictorial representation of a city block, and
anything else a good imagination can supply. For a
business, a typical use would be to map sales by Zip
code area. More examples are power usage by city
division, housing quality, number of McDonalds by
state, and so on.

The medium for MAPIT is the printer. In particular, it is
desirable to have a printer which has a condensed
mode of about 17 characters per inch across and 12
lines per inch down. Most of the inexpensive dot-matrix
printers have this capability and many letter-quality
printers do too.

The use of a printer for output means the resolution is
low. This fact is offset by the easy availability of
equipment and various techniques of display of the'
maps.

MAPIT gives you the maximum amount of map for the
minimum amount of work. Maps can be done over and
over with very little effort. You can get your pictures
"just right" without spending days on them.

Included with MAPIT are outline map files of the United
States, Canada, Europe, Asia, Africa, South America, and
Australia. Besides these base maps you can easily enter
your own maps. Once created, the outline maps can be
used again and again with different sets of data. So you
can map shoes this week and mineral deposits the
next—just by changing the data set.

Requires 128K and one disk drive.

Not only will MAPIT work with almost any printer, but
it also works with the HP 7400 series plotters.

Also available: 48-state county outline database.

SCREEN SCULPTOR

(IBM and compatibles only)

SCREEN SCULPTOR is a tool that allows you to design
and create customized input screen programs in
minutes, instead of hours. It is for anyone who is writing
a program in IBM BASIC, IBM PASCAL, or Turbo PASCAL
(all three capabilities are included in one package). The
source code that is generated can be modified or
merged with other programs.

SCREEN SCULPTOR is easy to use. First, it allows you to
design and create input screens by "drawing" them
directly on the screen. Then, it generates an actual
program based on the screen design.

Facilities include: easy color selection screen, special
character selection screen (to draw frames and boxes),
repeat-last-character in any direction, color painting,
move sections of text, and more.

The program code performs sophisticated data entry
functiqns such as using the cursor to move from field to
field, editing within a field (insert, delete, backspace,
arrows, etc.), character edit checking, range checking,
special field type definitions, error message displays,
and much more. Simply mark off the places where input
fields are to be located and, if you want, specify any,
special edit checking that should be performed (such as
special data types: numeric only, date, yes/no, etc.).

The generated code is designed so that special
modifications can be made easily by the user. Docu¬
mentation shows how and where certain modifications
should be made. The program code is documented.

Your benefits are:

• Saves time because SCREEN SCULPTOR generates
much of the program for you.

• Programs will look better. Designer screens can be
created in minutes. Program use.rs respond better to
programs that are visually pleasing.

• Data can be entered into programs more easily and
more reliably. The generated program will check the
data as it is being entered.

Program productivity is greatly improved because of the
time saved in creating attractive and sophisticated input
screens. The programs are bug-free and modifications
can be reprogrammed quickly.

For the IBM PC, PC XT, PC AT, PCjr, and true
compatibles. The program requires 128K of RAM, one
320K disk drive, DOS, and any 80-column display.

COUNTY OUTLINE DATABASE

The MAPIT U.S. COUNTY OUTLINE DATABASE in¬
cludes county outlines for all of the United States
except Alaska and Hawaii. This database can be used
with MAPIT or other mapping packages. The county
outlines are stored in 48 state files as ASCII text Each
county outline consists of a list of coordinate pairs
measured in radians X1,000. This allows county outlines
from two or more state files to be combined. Also
included is MTRANS, a program for scaling, docu¬
menting, and rotating map outlines, the DATABASE and
MTRANS sell for $95.00.

COLLECTION: MAPIT and the COUNTY OUTLINE
DATABASE may be purchased as a collection for

PLAYER MISSILE GRAPHICS
TOOLKIT

(Atari only)

DYNACOMP now offers three Atari graphics
development packages PLAYER-MISSILE GRAPHICS
TABLET (P.M.G.T.; page 25 of the Winter 1982 -
1983 catalog), PLAYER-MISSILE PLAYER EDITOR
(P.M.P.E. page 26) and PlAYER-MISSILE TOOL KIT
(described below). The first package helps you
create complicated backgrounds for your program.
The second provides an easy-to-use editor for
creating players and missiles, but presupposes that
you already have some knowledge of how to use
these players.

The third offering, PLAYER-MISSILE TOOL KIT is an
expanded version of P.M.P.E. which teaches you
the basics of player missile graphics and also
provides very professional and easy-to-use tools for
graphics development. The documentation (21
pages) is clearly and concisely written (it is excellent!).
It carefully explains what player-missile graphics
are, and the elements of their use.

The package also includes three programs:

1. PMINIT - a program to be included in your
own code which facilitates the operation of
PM graphics. This program pokes into memory
machine language software which greatly
speeds up player movement

2. PMBUILD - A P.M.P.E. which helps you
quickly construct players and missiles for
inclusion in your program.

3. PM DEMO - A classy demonstration program,
complete with a program listing and comments,
which clearly shows the use of PMINIT and
how simple it is to create graphics.

To really test this package, it was given to a
DYNACOMP employee who had never used player-
missile graphics, and who hates games. He came
back very pleased and excited about writing an
animation (as he called it). He was so enthusiastic
that DYNACOMP had him write this description!

FLIPSKETCH

(Atari Only)

FLIPSKETCH combines a powerful drawing program with
exciting and impressive animation features. FLIPSKETCH
uses low resolution graphics to allow you to create as
many screens as possible. A16K system lets you produce
8 screens, 24K allows 24 screens, 32K allows 40 screens,
and 40K allows 56 screens. The screens include one
background frame. Up to 24 different colors may be
selected for each screen. You use a joystick to design
each frame. Then you may animate (slow to rapid) your
work in one of two'ways: sequential animation, where
each screen is displayed in the order in which it was
created, or programmed animation, where you may
display screens in any order you desire. With pro¬
grammed animation, you can display up to 300 frames.

ENGINEERING SKETCHPAD

(IBM only)

ENGINEERING SKETCHPAD is a simple graphics pro¬
gram for engineers, technicians, architects, interior
designers, or anyone who frequently uses a straight¬
edge, compass, and templates to make drawings for
documentation and explanation. ESP-generated draw¬
ings are quickly and easily prepared, printed, and
modified. ESP is not a "paintbrush" program for general
art. These are usually poorly suited to engineering
drawings. Instead, it draws on a 5,000-point Cartesian
coordinate system to allow the preparation of easily-
read drawings (transistors, resistors, desks, etc.). These
stored drawings can be rotated, mirrored, inverted,
expanded, or contracted before being included in a
new drawing. In addition, structures may be "dragged
about" to simplify positioning them.

ESP is menu-driven to make it easily learned and
retained. It comes with a concise instruction manual
that also serves as a training guide with examples to
help you quickly master drawing techniques.

This package was written by a working engineer to make
his own job easier, and is published by DYNACOMP in
the belief that useful, convenient software need not be
expensive. The package includes documentation and a
disk containing the compiled program, the PASCAL
source code, and many electrical-engineering template
drawings.

ESP requires 128K of RAM, the IBM graphics board, two
disk drives, a printer, and a graphics screen dump

Your work can be saved on cassette or diskette for later
retrieval. (Diskette version includes a sample animation
sequence.)

Screen creation is made simple by use of the joystick and
many convenient commands (line drawing; area "fill";
image moving, inversion, reflection, fading; backgrodhd
merging; image "subtracting", superposition; and so on).

Requires 16K minimum (cassette), 24K minimum (disk¬

THE SHAPE MAGICIAN

(Apple II, 48 K Diskette)

The Apple II has several very powerful graphics features
which include the ability to define shapes in a "shape
table". The shapes may then be drawn, rotated and scaled
on the high resolution graphics screen. This ability is useful
for applications which require the repetitive drawing of
similar shapes at different locations or angular orientations.
Unfortunately, designing and entering shapes by hand is a
tedious and error prone process, and changes are very
difficult to accomplish once the table has been entered.

THE SHAPE MAGICIAN was designed to make the applica¬
tion of shape tables easy for even novice programmers. A
25 x 25 point grid is drawn on the screen and a graphics
cursor moved on the grid to define a shape. The actual
shape being defined is simultaneously displayed as it will
finally look on the high resolution graphics screen. After a
shape has been created, it may be stored on a diskette for
later recall by an application program. Shapes may be
edited and changed at any time.

THE SHAPE MAGICIAN includes complete documentation
describing how to use shape tables in your own high
resolution graphics applications. If you ever have wanted

VIDEO BILLBOARD

(Atari only)

VIDEO BILLBOARD is an exciting new program that
makes it easy to design and display colorful text-oriented
screens similar to those used on cable TV for announce¬
ments and advertisements. It can be used for advertising
displays, education, and home video titling. It is an ideal
attention-getter for conventions, store windows, and
shopping malls. Schools can use it for class notes, timed
tests, and educational TV.

Three character sizes, 128 colors, and flashing lines mean
high-quality attractive displays without expensive
specialized equipment.

VIDEO BILLBOARD displays can be controlled manually
like a slide show, recorded on a VCR, or run unattended.

The menu-driven user interface is backed up with help
screens and excellent documentation.

Up to 180 screens can be stored on a single floppy disk
and a free-running display can include them all.

An Atari computer with 48K of RAM and a disk drive are
required. An 80-column printer and printer interface are
optional.

Review of

VIDEO BILLBOARD

From ANTIC magazine, November, 1984

Video Billboard makes it easy for you to create fancy text
display sequences in multiple colors and different sizes
of letters. It's a great tool for making title screens, in-store
displays, breaking new ground in video poetry, etc.

You can fill the screen with as many as ten lines of thirty
characters each, or as few as four lines of fifteen charac¬
ters—depending on which of the three text sizes you
pick.

You choose colors for text and background of each line.
For special effects, you can have any lines flashing. You
can automatically display a sequence of up to 20 screens
from RAM, or up to 180 screens from disk.

The documentation is vejy clear and full of helpful hints.
In addition, fifteen screeens of on-line help are available
at any time. Also, you can obtain printouts of your
screens. If you have a need for an easy-to-use elaborate
text display, this program is for you.

to write programs using graphics, but found the programming
required too tedious, then THE SHAPE MAGICIAN is the
answer to your needs.

OSBOARD

(Osborne only)

NOTE: OSBOARD was originally distributed through
Osborne Computer Corporation. It is now dis¬
tributed through DYNACOMP.

OS BOAR D is to graphics what a word processor is to text
OSBOARD allows you to easily create graphic screens
using every possible graphic (or alphanumeric) character
and video attribute built into your machine. Here are
some of the review comments:

"greatly enhances the versatility and Usefulness of
the machine. Any Osborne user interested in ex¬
ploring the computer's graphic potential should
seriously consider this fine program."

George Taylor/Portable Companion

"This is the most comprehensive assembly-language
graphics package evaluated by ON. (The manuals)
are excellent and user readable.”

Earl Holland/ ON-the Osborne Newsletter

In addition to screen graphics, you may print your crea¬
tions (see the OSGRAPH description for compatible
printers). OSBOARD files may be converted (using
CONVERT programs supplied) into formats which make
it easy to add graphics to BASIC, CBASIC or assembly
language programs. A number of sample graphics files are
provided to demonstrate the powerul capabilities of this
package.

Available in two versions (state which you want):

OSBORNE 1: Allows you to create graphics screens

OSBRIEF

(Osborne only)

NOTE: OSBRIEF was originally distributed by the
Osborne Computer Corporation. It is now dis¬

Now you can create eye-popping graphic displays with
ABSOLUTELY NO PROGRAMMING! That's right - NO
PROGRAMMING! While most graphics editors (includ¬
ing our own OSBOARD) allow you to easily display files
using BASIC programs, OSBRIEF allows you to sequence
and display any number of graphic screens by just listing
the file names in the order you wish to have them
displayed — OSBRIEF does the rest! OSBRIEF is de¬
signed for use with graphic data files created with
OSBOARD or with charts and graphs created with
OSCRAPH.

OSBRIEF is the ideal tool for creating automated brief¬
ings, electronic slide shows, self-running demonstrations,
sales aids, or for just about any use that requires attended
or unattended presentation of graphic data.

A typical OSBRIEF presentation is controlled by a master
file which you create with Wordstar. The master file
contains the names of the graphics files to be displayed,
the order in which they will be displayed, the "special
effect" to be used to write each file to the screen, and the
amount of time that each file will remain on-screen.
Eleven spectacular special effects are available including
four "wipes" (left-to-right, right-to-left, top-to-bottom,
and bottom-to-top), fade-in and fade-out, curtains open
and close, push up and push down, spiral, and more!

An OSBRIEF presentation must be seen to be appre¬
ciated. Each screen may be displayed from 1 to 99
seconds or it may be frozen on-screen until any key is
pressed. The master file may also contain special com¬
mands to paint the screen white, black or gray as well as a
command which causes the demonstration to repeat
until halted. *

The OSBRIEF package includes a bonus utility program
called CHANGE. CHANGE converts ordinary text files
ffcqm Wordstar, SuperCalc, etc.) into a format compat¬
ible with OSBRIEF, making it easy to interweave text and
graphics in your presentations.

The Osborne 1 version of OSBRI E F automatically handles
files of all standard widths (i.e. 52,80, and 104 columns).
The Executive version is "upward compatible" with the
Osborne 1 version; that is, it will read and display all
files—even those created on an Osborne 1.

OSBRI EF is very "user friendly" and its clear and easy-to-
understand manual and helpful error messages will help
you to get your presentations "on the air" in a minimum
of time.

Excerpts from a very positive review
of:

DATA PLOTTER

(by Bruce Gale, Profiles Magazine, April 1985)

"Before using Data Plotter I had purchased two other
graphing programs for my Kaypro and examined sample
printouts from three more. The quality of the graphs
produced by Data Plotter is better than anything I had
seen before. I have also been quite pleased with its
'friendliness.' For example, error messages, which are in
English, are very clear (e.g., 'Label won't fit: too long or
badly placed.') Data Plotter permits you to re-key your
entry and ignores all incorrect entries when it creates its
plot file. The manual is 78 pages long and is well written,
with good examples.

"I highly recommend this program to anyone who
needs to make high-quality graphs. If you have a
computer that does show graphs on the screen, you
may want to run rough drafts with that program, but
you'd be hard pressed to beat the hard copy output
produced by Data Plotter. I frequently use Lotus 1-2-3
for data analysis onscreen, but I print the final form to a
text file and use Data Plotter to produce graphs for my
reports and presentations."

OSGRAPH

OSGRAPH is a business graphics package which can
process just about any data source (hand-entered data,
SuperCalc, dBase II files, MBAS 1C program output, and
more) into high quality horizontal or vertical bar charts,
pie charts, or XY plots.

OSGRAPH is menu-driven, with chart parameters which
can be changed at any time and their results displayed on
the screen. Charts may be saved on disk and recalled for
editing or printing. Charts are automatically labelled or
custom labels may be used. Output print width is 80
columns. Works with the following printers: Epson (with
Graftrax), IDS Prism 80/132 (with Dot-Plot), Microprism,

DATA PLOTTER

(CP/M and IBM only)

DATA PLOTTER is not a "screen dump" program. It does
not create graphs on the screen, but rather on your
printer. That means you can use DATA PLOTTER with
your Kaypro, Morrow, Osborne, IBM (with or without
graphics), and other CP/M machines.

Here are some of the features:

• Unlimited number of labels placed anywhere on the
page.

• Uneven spacing of points (either axis).

• Unlimited number of functions on one graph.

• Automatic manual scaling.

• Choice of graph size.

• Choice of numbers, words, or both as labels for X and Y
axis divisions.

• 11 different symbols in six sizes for line graphs and
scatterplots.

• Distinctive shadings for pie charts and bar graphs.

DATA PLOTTER plots data from an ASCII (text) file. This
data can therefore be created by a word processor,
dBASE 11, SuperCalc, a program you have written, etc. You
do not need to program to make DATA PLOTTER graphs.

DATA PLOTTER asks you a series of question which let
you design your graph with great flexibility. However, you
do not have to answer these questions each time you
want to make a graph. Instead, the answers can come
from a previously saved file. You can use these answers
repeatedly with different sets of data, or edit them to alter
the graph's appearance. As you can imagine, this can be a
real time saver.

DATA PLOTTER is used by many scientists, researchers,
professionals, students, analysts, executives, and sales
people. DATA PLOTTER graphs have also appeared in
many professional journals.

The final point to note is that DATA PLOTTER is excep¬
tionally easy to use and comes with a very clear manual.

Requirements: CP/M versions require 48K of RAM.

IBM version requires 128K of RAM.

These dot-matrix printers are supported: Anadex, BMC,
Centronics, C. Itoh, DEC, Epson, Pacit, GE, IBM, IDS,
Mannesmann Tally, Okidata, Star Gemini, and others.

PLOT!

(IBM only)

PLOT! allows you to plot and process data or curves (or
both) described by mathematical functions.

Most of the instructions on how to use the program are
given on the screen with different options selected by the
function keys. No information about minimum and
maximum values, tics, or scales is required.

The processing features allow you to switch back and
forth between linear, semi-log, and double-log scales, to
calculate and plot the inverse, power, and linear func¬
tions of the data points. You can calculate slopes, add
data stored on a diskette to the data entered from the
keyboard, and find and plot the least-squares fit to the
data points.

Labels can be easily placed anywhere on the graph. They
can be entered from the keyboard or read from diskettes.

Any data of labels can be easily corrected without re¬
entering the rest of the information.

A created graph may be stored on a diskette.

All the information contained in the graph may also be
printed in a concise and clear form by simply pressing a
function key designated for this purpose.

In order to run PLOT! you need an IBM PC with a
minimum of 64K of RAM, a color graphics adapter, a
single- or double-sided disk drive, and PC DOS or MS
DOS with BASICA.

If you have DOS 2.0 and an IBM graphics printer (or an
EPSON printer with CRAPHTRAX or GRAPHTRAX-plus
option) you may use the DOS GRAPHICS utility to make a
hard copy of your graphs.

GENERAL UTILITIES

CP/M-80 EMULATOR
FOR THE IBM-PC

(IBM only)

Now, using ZP-EM, you can run CP/M-80 software on
your IBM-PC! For example, you can use dBASE II, Micro¬
soft BASIC, ED, etc. All you need do is boot the ZP-EM
8080 microprocessor emulator to get the A> prompt,
and the world of CP/M-80 software is available to you!

ZP-EM is a machine-language 8080 microprocessor emu¬
lator which gives your IBM-PC an effective CP/M pro¬
cessor speed of about one megahertz. Its only limitations
are that it cannot handle code which contains Z-80
specific instructions, modifies the operating system, or
accesses the hardware directly. Using the IBM display
characteristics, ZP-EM will emulate Osborne, Kaypro
(ADM-3), HZ-19, and DEC VT52 screens.

If you have CP/M-80 software you want to run on your
IBM, here is your chance.

Requires MS-DOS 1.0 or higher and 192K of RAM.
Price: $39.95 Diskette

Collection: Let's face it, ZP-EM is not very useful unless
you can get your CP/M software onto an MS-DOS
diskette. Therefore, it makes sense to offer ZP-EM and
MEDIA MASTER (see DYNACOMP's price and descrip¬

MEDIA MASTER

(Osborne, Kaypro, Z100, and IBM only)

Note: Just as we went to press, the IBM version of
MEDIA MASTER was released. It handles 75 disk
formats!

This is one of the most useful programs that you can get
for your double-density Osborne! We use it every day!

The problem today's Osborne owner faPes is lack of
available software. Only a few companies, like DYNA¬
COMP, continue to support the Osborne. Now, with
MEDIA MASTER, you can work with diskettes written on
the following machines:

A OSBORNE DD .

B; OSBORNE SD

C. DEC VT 180

D. IBM PC CP/M

E. IBM PC DOS 1.0

F. IBM PC DOS 2.0

MEDIA MASTER is simple and very easy to use. In essence
you can set each of your two drives to a different format.
For example, you can set drive A to KAYPRO 11 format and
Drive B to IBM MSDOS. Then you can move files be¬
tween those drives at will. Here is the menu of operations
you can perform:

Copy files

Print directory

Display directory

Set drive to specified format

Erase files

EC DISK CATALOGER (Release 3)

(CP/M only)

EC DISK CATALOGER is the Cadillac of disk directory
systems. Use it to quickly and easily catalog your disk
library by just sticking disks in your drive. Briefly, here are
some of the features:

• Catalogs disks smoothly one after another. No need to
exit the program and press CTRL-C to reset drive for next
disk. Safely recovers during cataloging if catalog disk is
full. Includes all user areas. Up to 500 files per d/skcan'be
cataloged (for hard-disk users).

• Full-screen menus and displays.

• Select desired disk to display or search by "pointing"
to its name on the sccreen, not by entering a cryptic disk
number.

• Directory and other listings are alphabetical, with file
sizes and space remaining on disk, and can be directed
either to the screen or to the printer.

• Searches catalog for specified file name, wild-card file
specification, or key word.

• Prints disk labels containing disk directory
information.

ATARI UTILITIES

(Atari only)

DYNACOMP is offering ATARI UTILITIES both as a
goodwill gesture and also to make our own lives
simpler. The DYNACOMP diskette contains four
programs: A (sorely needed) RENUMBER program,
a disk RPM test program, and two programs which
draw portraits of the Atari 400 and Atari 800 (cute,
but really not very useful). The line renumbering
routine is for those who program and have been
frustrated by the absence of this common function
in Atari BASIC. The RPM test program allows you to
check (and adjust) your disk speed to meet the
original specifications. We have ulterior motives
here: If your drive s^eed is accurate, then your
DYNACOMP software will load more reliably and
you will not be calling DYNACOMP and telling us
about a 138 or 144 error. Our price simply covers our
costs:

GENERAL UTILITIES

DIVERSI-DOS

(Apple only)

Here is a disk operating system (DOS) for your Apple
which has tremendous advantages over that supplied
by the original manufacturer. First, DIVERSI-DOS
speeds up your disk input/output by a factor of 3 or
more, which is very noticeable for mail list, financial,
engineering, etc. programs. Second, DIVERSI-DOS
includes a keyboard buffer; you can type ahead as
fast as you want Third, with a 16K RAM card (which
incidentally, DYNACOMP sells at a low price), you
can buffer your printer output ("spool"). Fourth,
DIVERSI-DOS can move itself to a RAM card to
increase space for BASIC. And more!

Now for the surprising part. DYNACOMP's price is
$5.00 for the diskette plus $3.00 for the documen¬
tation. When the diskette is delivered "it is then the
responsibility of the customer to send a $25 license
fee” to the original publisher. Since DYNACOMP's
sales are confidential, it is up to you and your
conscience to send in the license fee. We think this
is a very noble experiment and we will be comparing
our net sales figures with the publisher's license
returns (please mention that you got DIVERSI-DOS
from DYNACOMP). Requires 48K, one disk drive.

Price: $5.00 for the diskette plus
$3.00 for the documentation
NOTE: DIVERSI-DOS now contains the game DOG¬
FIGHT, an arcade game for the Apple.

Note: DIVERSI-DOS cannot be included in volume dis¬
counts.

• All disk directories can be printed to an ASCII file.

• On-line help screen for each catalog function.

• Date can be entered and will appear on all listings.

• Thirty page user's guide.

Requires a Z-80 based microcomputer with 64K and
CP/M 2.2 or 3.0; two disk drives; 80-column x 24 line
cursor-addressable terminal (or computer); 80-column
printer (if listings are desired).

If you value your time and software collection, you will
find this to be one of your best investments.

SCREEN MASTER

(Atari only)

SCREEN MASTER is a program that writes programs
for you. It allows you to move a cursor about the
screen to create displays or "panels", such as menus
for programs or any other kind of text display. You
can create panels in ATARI text graphics modes 0,1,
or 2. Simple commands allow easy repositioning of
text on the screen. When the panel is done, SCREEN
MASTER actually writes the BASIC statements that
will reproduce the panel you have designed and
stores them on disk. Later you can insert these
program lines into another program you might be
writing, or recall them from the disk for further
editing. All the functions performed by SCREEN
MASTER are selected from a menu. SCREEN MASTER
makes it very easy to create visually pleasing and
effective text displays.

Requires 32 K.

GENERAL UTILITIES

PC CATALOG

(IBM only)

PC CATALOG is a diskette management utility that
helps you keep your diskettes organized. It simplifies
the task of locating a program or file, is a great aid in
keeping track of where diskette space is available, and
helps prevent needless duplication of a file over several
diskettes.

PC CATALOG uses menu driven display screens, full¬
screen data entry, program function keys, forward and
backward screen scrolling, and an on-screen help
facility. An options file can also be set up, eliminating
the need to re-enter repetitive information.

Directory information is automatically captured by
reading the diskette directory and storing the infor¬
mation (file name, volume label, file size, creation date,
and time) in a user catalog file. Optional 40-byte
comments may be added to each directory entry. The
catalog entries are sorted and stored in alphabetic
filename sequence and may be displayed or printed.
Diskette labels may also be printed.

Includes full path name support
Requires two drives and 256K of RAM.

Price: $29.95 Diskette

UTIL

(Apple only)

This APPLESOFT program runs on a 48 K APPLE II with
access to APPLESOFT. UTIL will operate under DOS 3.2
and 3.3. UTIL will start by asking you to insert the diskette
you wish to process. It will pause for you to insert the
diskette you want to examine into the disk drive. UTIL will
then read the diskette to determine the initial parameters
it is to use (such as 3.2 vs. 3.3). The MENU page is then
displayed.

The MENU shows the list of options available in UTIL,
along with the currently selected slot/drive and track/sector
numbers. As is the rule in UTIL, these numbers are
displayed in hexadecimal The following options are
available:

DATA FILE TRANSLATOR

(CP/M and IBM only)

CP/M and MS-DOS DATA FILE TRANSLATOR was
designed to address a need which we have at DYNA¬
COMP and which has been described by many whp
have called or written to DYNACOMP. There are many
software packages in existence today (e.g., statistics,
engineering, spread sheet, personal finance, etc.) which
create random and/or sequential access data files. In
most cases, the files generated by one package are not
strictly compatible with those created by others. This
has caused a great deal of inconvenience for those who
want to use the same database with different software
packages. To compound things, the file structure
employed by these programs is generally not described
in the associated manuals since the user has no need to
know the details (when using just that one package).
Therefore, what do you do when you want to use
MULTI-LINEAR REGRESSION with your VISICALC data
files?

To deal with this situation, DYNACOMP has written a
software utility which permits you to unravel your data
files and convert them to other formats. With CP/M and
MS-DOS DATA FILE TRANSLATOR you may read multi-
variable sequential files, edit those files, and write
selected variables to random access files having the
structure you define. You can also read from random
access files, edit, and create sequential files. Sequential
files may be changed in format, variables extracted from
parts of sequential files edited, and written to other
sequential or random files, and so on. In other words,
you have complete flexibility in manipulating data files
and splitting data out from random or sequential files.

In addition, if you do not know the file type or structure,
CP/M and MS-DOS DATA FILE TRANSLATOR allows
you to easily and conveniently probe the file to find out
what type it is (random or sequential) and what its
structure is.

All of the TRANSLATOR'S functions are menu driven.
Further, once you have determined the correct transla¬
tion procedure, no matter how complex or arduous, you
may save the procedure on disk so that in the future, the
manipulation can be done automatically!

Another feature which has been included to help you
identify data sets is a facility for plotting. All plots are
done using alphanumerics, and may be sent to your
printer.

Also, in our testing of the TRANSLATOR we found that
people who had no prior experience in dealing with file
structures quickly learned about random and sequential
files and their formats, learning by experiment

Quite frankly, we do not know why this type of utility
has not been commercially available until now. The
need is clear and pressing. Why didn't we write it a few
years ago?

Requires at least 48K and one disk drive A printer is
supported but not necessary. Requires BASIC

of people... all across the country—and you beat the
long-distance phone rates!

• Electronic Mail: “You can send private messages or
letters to any other subscriber.

• Bulletin Boards: You can post announcements, or
check bulletins posted by other people. There are
several bulletin boards for different hobbies and
interests.

• Personal File Transfer: You can exchange programs
or files with other PlayNET subscribers.

• Software Library: Thousands of public-domain
software programs are availabe for downloading to your
computer.

• Software Trading Post: You can sell your own
software creations for fun and profit

• On-Line Updates: You can update your PlayNET
disks on-line as new games and features are added to
the PlayNET system.

• PlayNET Shopping Center: You can order software
and other exciting products on line.

free, where everyone gets their own screen identity.

• Games: PlayNET lets you play exciting multi-player
games across the country with anyone on the PlayNET
system! All the games have full-color graphics, and
they're all interactive.

Here is what RUN magazine (August, 1985) had to say
about PlayNET: "This is a great opportunity to meet
people from all across the nation and share ideas and
opinions with them. Your home computer can broaden
your horizons by giving you this chance to travel
beyond your own hometown."

PlayNET also has surprisingly low access charges. You
can either pay an $8.00/month service charge and
$2.75 per on-line hour, or no service charge and $3.75
per on-line hour.

So far this sounds like quite a deal, but there is even
more! With the PlayNET starter kit you also get two
game disks which include BACKGAMMON, CAPTURE
THE FLAG, CHESS, CONTRACT BRIDGE, GO, QUAD
64", SEA STRIKE", BOXES, CHECKERS, CHINESE
CHECKERS, HANGMAN, REVERSI, and GOMOKU.
These are not one-player games; you must play against
another person. This can be accomplished by placing a
request on the network to find another player; a very
pleasant way to meet people!

PlayNET is very easy to use. It is clear and menu-driven.
Connecting up is simple, and the 66-page manual walks
you through all of the steps and facilities.

The PlayNET STARTER KIT contains all of the software
you will need to sign on. Note, however, that you must

ADVENTURE GAMES

BUTLER ADVENTURE

(CP/M and IBM only)

For young people (7-11)

BUTLER is an adventure-type game that is intended to be
both entertaining and educational. The game requires
that the player read the descriptions and keep track of
where the objects and the player are. Id order to move
between certain places, the player must solve word
scrambles or arithmetic expressions. A floor plan (map) of
the mansion is provided. The map helps younger players
to see their progress and helps to maintain their interest
and attention. More advanced players can begin playing
with or without the map. Mapping the game as they play
provides an extra challenge for older children. The game
remains challenging even with the map and many adults
find the game challenging. The game, however, is not
extremely difficult and will not prove impossible to solve
for any child from seven to eleven years old.

The game has three levels of difficulty: low, medium, and
high. At the low-difficulty level the arithmetic expres¬
sions are limited to simple addition problems and the
word scrambles are restricted to words of three or fewer
letters. The medium-difficulty level uses arithmetic ex¬
pressions that include addition, subtraction, multipli¬
cation, and division of integers between 0 and 9.
Medium-level scrambles are limited to words of six or
fewer letters. The highest level of difficulty allows inte¬
gers between 0 and 99 and words of up to nine letters.
The difficulty levels are associated with the moves that
require solution of problems only. The balance of the
game is the same regardless of the difficulty level chosen.

The game is won if the player succeeds in getting 225
points in 190 or fewer moves. Points are awarded for
successfully storing in the vault the 13 items that are
listed at the beginning of the game. Points are also won
for finding certain "hidden" rooms, for putting everything
in the vault, and for exploring all of the rooms in fewer
than 190 moves.

The program responds to about 20 verbs such as GO,
LOOK, TAKE, and PUT, and about 40 nouns, including 12
directions such as NORTH, EAST, UP, DOWN, BACK,
SOUTHWEST, and IN. The game encourages players to
try a variety of one- and two-word commands in order to
test the limits of the game.

Requires 48K.

THE CP/M GAME DISK

(CP/M only)

DYNACOMP has long been the mayor source of diversi¬
fied software for the CP/M environment. In particular,
DYNACOMP is one of the few companies which supplies
games for general CP/M machines.

Usually dur games require Microsoft BASIC to operate.
This group is an exception. The three games contained on
THE CP/M GAME DISK are written in machine language
and will run under any CP/M system having an 8080/Z80
compatible microprocessor (e.g., Xerox 820, Altos, North
Star, Osborne, etc.). In addition, these programs utilize
the cursor controls of your video terminal. This is ac¬
complished by running an "installation" program which
allows you to choose a particular terminal, or define your
terminal characteristics. Cursor control is required be¬
cause two of the games are arcade in nature.

THE CP/M GAME DISK contains three different pro¬
grams:

1. THE GAME ADVENTURE: This is a very large adven¬
ture program which has several features. For example,
you not only open doors, pick up and drop things, etc.,
but you also meet people and have conversations. Also,
part of the game is to figure out what the goal is, based on
clues you are given (messages, comments from people
you speak to, etc.). This is quite an involved game, and
will take many sessions to solve (you may save your
current game and continue it later).

Age range: 12 and up

2. ALLEY CAT: This is an arcade game which uses
alphanumeric characters to create a PACMAN*-like ani¬
mation. The effect is surprisingly pood. Your cat is roam¬
ing the streets trying to find fish in garbage cans.
However, there are fast taxicabs also cruising those
streets. Your goal is to go chomp and not splat.

For players ages 10 and up.

3. BOWLING: This is another arcade-like game. It is
fairiy simple. You have to position your ball and then
deliver it. It will then roll down the alley and hit pins. The
cortiputer keeps score.

Age range: 8 to 13 .

Requires a Z80 microprocessor, at least 54K, a video
terminal (display), and one disk drive.

or medical care.

Help-wanted locations provide a quick way to make
money.

LOS ANGELES ON A DISK is a one- or two-player game
which can be played by anyone 10 years of age or older.

the few computer games that an adult can play better
than a child.) You can start out on level 0 for sightseeing
or choose more difficult play through level 9. There are
various modes of transportation in the game including
walking, driving, and flying. For traveling great distances
quickly, you can use one of the eight airports.

WINDMERE ESTATE ADVENTURE

(North Star and Apple only)

The WINDMERE ESTATE ADVENTURE is an exploration
simulation. You start in the Rose Garden on the grounds
of Windmere Estate. Using the computer and two-word
sentences, you attempt to find all the treasures and
deposit them safely at the treasure drop. There are a
number of puzzles to solve ?e.g. how to get to the
Warehouse). There are some tricky areas where caution
should be exercised or you will not survive. The key to
winning the game is to successfully discover and enter all
the hidden rooms (which abound).

The object of the game is to score all the points. Each item
considered a 'treasure' has a number of points assigned
to it, and the points will be credited to your score when
that item is DROPPED at the Warehouse. When the last
treasure is DROPPED at the treasure store, you will arrive
at the last puzzle of the game. A successful solution to
that problem gives you the final victory!

The computer will recognize many one- or two-word
commands including quite a few verbs and nouns. Exam¬
ples: HELP, QUIT, LOOK, NORTH, N, SE, and DOWN.

This is not a complete list by any means. Some two-word
commands are: CO SOUTH, POUR WATER, and TAKE
ROPE. In some cases, where you are determines the
validity of a command (CLIMB, ATTACH ROPE, etc.) At
other times a command will be valid only if you have
some special item in your posession (PRY GATE). There
are also cases where some previous action must have
been successful before a command is valid (e.g. TAKE
RATS).

On occasion you will find an item that is obviously not a
'treasure'. An example of this is a lamp. This can be carried
about and used to light dark areas (use LIGHT ON, or
simply ON to start it. Use OFF to turn it off to conserve
power.) There are many other useful items lying around
for your use. You are allowed to carry only seven items at
one time — unless you can set one inside somethingelse!

Circumstances sometimes arise, particularly with an in¬
experienced player, that will cause the player to die.
There are some bats flying all over the place, and these
bats are deadly! There is one sure repellant available
somewhere out there. Stumbling in the dark or stepping
into dark holes are other ways of doing yourself in.

Requires 48K.

GENESIS - THE ADVENTURE
CREATOR

(Apple only)

Until now, if you wanted to write an adventure
game, you needed lots of time and considerable
programming skill. Such a task requires you not only
to create a world- the fun part- but to writejoutines
to keep track of everything taking place in it - the
drudgery. Now however, there is GENESIS. GENESIS
removes this drudgery from creating adventures.

You design your world - GENESIS programs it.

GENESIS has two parts. The Creator allows you to
create and edit your adventures. The Player allows
you, or anyone else, to play any adventure you have
created. After you get a feel for the system, you will
probably be able to create a moderate sized game of
about thirty-five locations in one to two hours - a
great improvement over the weeks or months it
would take were you doing the programming
yourself in BASIC or another language.

A 60-page "how-to-do-it" manual is included.

NOTE: GENESIS was originally published by HEXCRAFT,
and is now published by DYNACOMP. See review in
Softalk. Requires disk drive, 48K RAM.

GUMBALL RALLY ADVENTURE

(North Star, CP/M, and IBM only)

The C UMBALL RALLY ADVE NTU RE is based loosely on the
movie "Gumball Rally". It is an outlaw race from the East
Coast to the West Coast by any route you choose. You can
go as fast as you want; but, if you crash or get thrown in jail
for reckless driving, you lose! Ordinarily, you would have a
map to plan your route; but, as every true adventurer
knows, you must draw your own map! In the movie, the
winner won a gumball dispenser of the type you used to
find on the sidewalk in front of drugstores. Hence, the
name.

In this adventure, your goal is to first find your way to the
finish line, and second to maintain the highest possible
speed on all roads. Your choice of vehicle will determine
your maximum speed and your range. (Big-engined cars
burn more gas!) There are gas stations along your route
where you can refuel when needed. Your score depends
on your average speed.

COMMANDS

As in most adventure programs, you "talk" to the computer
in one-word or two-word commands. For example, "GET
CAS" or "FIX TIRE". In addition, in this program, you
control the speed of your car by typing a number
representing the speed you wish to travel. Your speed
around turns or on curvy roads will depend on the
sharpness of the turn. The sharper the turn, the lower the
maximum safe speed. On straight stretches, you can go
as fast as your car will allow, but you must decelerate
before enteringa turn. Failure to decelerate may result in
your demise! !

CUMBALL RALLY ADVENTURE will provide you with
many hours of enjoyment.

thieves. Wingster is inhabited by Dwarves, Elves,
Hobbits, and Man. It is also a land of countless monsters
and beasts created by the "Dark Side'V

There are many special features of MIGHT & MAGIC. The
game allows players to create and store their characters
on the MIGHT & MAGIC side of the disk. Because
countless traps and monsters are encountered during the
adventure, MIGHT & MAGIC incorporates a unique
combat system featuring round-by-round combat.
During each round the player may select the character's
weapon and tactic for that round of combat. Players may
also save their game at any time during the adventure.
The character's data, special abilities, and equipment
may be obtained at any time showing the player every¬
thing about the character. Throughout the adventure
there is a two-line status display giving the location,
hunger, need for sleep, power points, time, and physical
condition of the character. There is also a complete rule
book on the disk for easy reference.

The dungeon adventure on the back side of the MIGHT &
MAGIC disk is THE LAVA PITS OF AZNAR. In this
adventure the players pit their strength and wit against
the awesome forces which dwell in the volcanic dungeon
during their quest for the amulet of the "High Lord of

BRIDGE PARTNER ALICE

(CP/M and IBM only)

ALICE is an ABSOLUTELY UNIQUE bridge bidding and
playing program. There's nothing like it anywhere. It has
features for both beginning and advanced players. If
you want to just sit down and play some good bridge,
get DYNACOMP's BRIDGE MASTER or BRIDGE 5.2.
However, if you want to really delve into bidding,
consider ALICE.

ALICE'S bidding method is very sophisticated and
operates in two modes: practice and learning.

BIDDING PRACTICE

ALICE comes already programmed to bid Standard
American Five Card Major. She was given a lesson (more
about this below) in this method by a professional
bridge instructor. She will respond to conventions such
as the Blackwood. Her bids are based on point counts,
high card location, suit distribution, and the sequence
of bids. There are approximately one million hands to
choose from by number, and any hand can be recalled
again for either bid or play.

BIDDING LEARNING

When ALICE first arrives at your doorstep she knows
how to bid, but should be taught more. The more you
teach her, the better she will bid by your method. This is
a true example of artificial intelligence.

In the learning mode, all the hands are turned up.
ALICE will bid for each of the three other players. Each
time she bids you can either accept her bid or you can
tell her what a better bid might be. She will evaluate
what you told her and store that information.

The advanced player can use this mode to really fine
tune ALICE by adding conventions, including your own
signals, etc. The beginning player can use this mode,
together with a book on bridge, to learn with ALICE! In
any case, you will get a chance to bid on many hands
and think about bidding. (Some companies market
programs which just provide hands for bidding!)

After bidding a hand, you may either play it or go on to
another bid. You can play with all hands showing (that's
cheating, but it is informative). You can also choose to
have ALICE play all four hands. For the beginning player
this is a real advantage in that you can see what the
appropriate plays are and, in particular, how to finesse.
Also, if the rest of the game is obvious, ALICE can
automatically play it out (an honest approach to
claiming).

ALICE uses standard opening leads (e.g., king from
touching ace-king, fourth from the "longest and
strongest," etc.). She will take finesses, lead to promote
tricks, etc. In other words, ALICE is a decent player.

ALICE requires at least 64K of RAM and two disk drives
having 160K (or more) of storage capacity.

CASINO

(TRS-80 only)

CASINO is the card game that was in vogue prior to the
advent of Gin Rummy. It is still very popular and is often
taught by grand parents to their grand children.

The DYNACOMP version uses two players: you and the
computer. The computer plays a fairly strong game and
(of course) keeps track of scores, shuffles, deals, etc. The
cards are shown on the screen using TRS-80 graphics. All
the features of standard casino are included.

CASINO comes with a complete instruction manual
which includes a section on the rules of the game, as well
as playing strategy. If you want to learn to play Casino or
are looking for a worthy opponent, here is your chance.

BRIDGEMASTER DOES IT AGAIN!

The BOOK OF ATARI SOFTWARE (1983 edition)

overall value for the dollar. We must be doing
something right: they gave PACMAN and SPACE
INVADERS a "C".

BRIDGE 5.2

(Commodore 64 only)

BRIDGE 5.2 is DYNACOMP's most advanced addition
to the BRlbGE N.N series, and was written and
compiled specifically for the Commodore 64.

BRIDGE 5.2 contains many of the features of BRIDGE-
MASTER™, but all in one large program. BRIDGE 5.2
both bids and plays. You may choose random hands or
specify them. The bidding method is standard American
and includes three level pre-emptive bids, take-out
doubles, the Blackwood convention, doubles and re¬
doubles, etc.

During play you may choose to ^ee only the cards
normally showing or opt to see all of the hands (double
dummy). You may review the cards dropped during the
last round and "claim" if desired. Hands may be
replayed.

Although BRIDGE 5.2 does not contain all of the
features of the multi-program BRIDGEMASTER, it is a
strong player and is available on cassette.

Price: $19.95 Cassette
$23.95 Diskette

BRIDGE 5.2 won the first microcomputer bridge
tournament for best defensive play (Midway Bridge
Club, New York, January 8, 1985), and has had a hand
published in the New York Times bridge column
(January 2, 1985). Its competitors included Troup's

DOUBLE-DECK PINOCHLE

(TRS-80 only)

DOUBLE-DECK PINOCHLE is simply the fastest (ma¬
chine language) and best-playing computer pinochle
program available. You may either play in the learning
mode or compete in a regular game. There are four
players, with the computer supplying your partner and
the opposing team. The game includes bidding, playing,
scoring, and a HELP mode. If you like to "meld", you will
love DOUBLE-DECK PINOCHLE.

BRIDGE MASTER II

(Apple only)

The usual customer evaluation of BRIDGE MASTER is
"excellent". So what could we do to improve an already
great product? Well, we did find a few things:

• We improved the bidding. More than 90% of the
time the right contract will be bid (if you hold up your
end).

• We improved the playing. Better finesses and
trumping, too.

• We added more options. Anyone can be the dealer;
assigned vulnerability; claiming.

BRIDGE MASTER II was tested for more than a year
prior to release because of its complexity. We think you
will love it!

BRIDGE MASTER II requires 48K and one disk drive.
Price: $34.95 Diskette

Upgrade: If you have already purchased the Apple
version of BRIDGE MASTER (I), you may upgrade to
BRIDGEMASTER II by returning your Apple BRIDGE
MASTER diskette with a check (Master Card, Visa, or
American Express) for'$10 plus $3.50 shipping and
handling. Make sure the diskette is well packed!

BRIDGE MASTER

(available for all computers)

If you liked DYNACOMP'S BRIDGE 2.0, you will absolutely
love BRIDGE MASTER. BRIDGE MASTER is a comprehensive
bridge program designed to provide hours of challenging
competition. Bidding features include the Blackwood
convention, Stayman convention, pre-emptive openings,
and recognition of demand bids and jump-shift responses.

The program plays the North hand as your partner and East-
West as your opponents. After playing a specific hand, you
may replay the same hand, with the option of switching
cards with your computer opponents. This feature allows
you to compare your bidding and playing skills to BRIDGE
MASTER.

A unique feature of BRIDGE MASTER is its scorekeeping
capability. Points scored for each hand are calculated.
Bonuses for game contracts and slams are awarded as in
duplicate bridge. Doubled contracts are scored based
upon a computer assigned vulnerability. Individual hand
scores are tabulated and an accumulative score card is
displayed at the conclusion of each hand played. The score
card displays a summary of total hands played, total points
scored, number of contracts made and set, and % bids
made

Requires 24 K program memory (Atari version requires
48K). Available on disk only.

Review of BRIDGE MASTER
AC E., January, 1983

BRIDGE MASTER

This program is available on disk for $29.95
from DYNACOMP, 1427 Monroe Avenue.,
Rochester, NY 14618. It is an upgrade of their
former Bridge 2.0. If you own the original, you
may obtain the upgrade by sending them your
original cassette or disk, together with $5 plus $2
handling. They wqre VERY prompt. I received the
disk in what seemed less time than was required
for my order to reach NY. I also sent off two pages
of questions, and they were also very prompt with
responses to the questions. Most of my problems
with the program was due to my lack of under¬
standing about Duplicate Bridge. I’ve never
played Duplicate. The documentation tells you
the program generates hands numbered from ‘0-
999’. A numbered hand produces the same card
distribution each time you select it. You may play
the same hand as many times as desired. You
may also switch positions in the same hand, and
see how you may do on the other side. The
documentation also tells you the ‘0’ hand produces
a random hand each time you select 0. I didn’t
find that to be true, and asked Dynacomp where

the random hand could be found. Their response
showed me the hands were actually numbered
from 0.00 to 999.99. That’s 100,000 hands,
instead of 1000. Who needs another random
hand generator? I hope I live long enough to play
100,000 hands (not likely!). The program keeps
score and saves it to a disk file so you can come
back to it any time. The menu lets you display the
last hand played. So if you’re playing the numbered
hands sequentially, if s easy to pick up where you
left off. There are no graphics- it’s all text. With all
the scoring and reading and writing to disk it
seems slower than the 2.0 version it replaces. It
has added some functions not covered by the
2.0. They’ve added pre-emptive openings,
Blackwood and Stayman conventions. The pro¬
gram will also recognize demand bids and jump-
shift responses. These are all nice improvements.
Dynacomp says “sometimes it makes dumb
plays!” I can second that! It makes them by your
partner, as well as by your opponents, so maybe it
evens out. Little things like trumping one’s own
high card, setting up an opponent’s loser. The
program makes you look like a very good Bridge
player - you can win a lot. It’s good practice for
someone wanting to learn to play. I think I’m a
pretty good player, and I’m having fun with it.

DUPLICATE BRIDGE MANAGER

(CP/M and IBM only)

The duplicate bridge player is often faced with the
choice of going home and wondering who won, or
following the strenuous session of bridge with a lengthy
period of scoring, adding, checking, and looking for the
reasons that the totals don't balance.

This collection of programs has been designed to assist
in the organization and to facilitate scoring of a session
of duplicate bridge.

To start, parameters are entered to define the game.
Specifically, Howell Or Mitchell movement, the
number of tables, number of boards, number of rounds
to be played, and whether there will be a half table.

Following these entries, the screen will show the starting
table, pair and board configurations, and give move¬
ment directions. A printed copy may be obtained if a
printer is available.

You enter the results of each round of play while the
next round is in progress. Otherwise, all scores can be
entered in one batch after play is completed. For this
mode, a quick-entry option is available. Each board is
handled as a batch of input. NS pair numbers are called
up in turn, their opponent pair number presented, and
entry of only NS score (+ or —) is needed for each play.
Thus, the operator need only key in the scores reading
from top to bottom of a conventional traveling board
score sheet.

The program provides error recovery steps to avoid loss
of data already entered and provides prompts which
make it unnecessary for the operator to remember
which results have been entered.

The program will summarize each board after all plays
are entered, and likewise will tally the overall results
after the last board's results are recorded.

The game may be terminated, and a tally initiated prior
to the planned end of play should an emergency or
unscheduled departure of one of the participants occur.

Factoring for varying numbers of boards played can be
accomplished after the plays are all tallied.

GIN RUMMY

(IBM, Z-100, and C-64 only)

This program is one of the nicest looking and best playing
card games we have ever seen. The author has combined
attractive graphics and sound into a program that is a
match for the best Gin Rummy players around. The result
is spectacular. This program is for one player against the
computer. It allows knocking, laying off, and all standard
game conventions.

IBM and Z-100 versions require 128K. A graphics card is
not required.

Price: $19.95 Diskette

These results (both board tallys, and the overall score

summary) are presented on the screen, and stored on

disk.

Any errors noted at summary may be corrected by re¬
entering correct values.

Other features:

• Basic key strokes per usual hand = 5

• In Mitchell Movements, either "skip" or "bye stand/
relay” movements are handled. In fact, the preferred
game is selected by the program upon entry of the
number of tables, rounds to be played, and couples
on hand.

• Incomplete movements are accommodated (e.g. a
twelve-table game with only eleven rounds).

• A game in progress can be abruptly shortened
(stopped) and scored.

• Variable tops are automatically handled in those
cases where boards are played differing numbers of
times.

• Factoring of grand tables is performed for pairs
which have played fewer than the maximum boards.

Includes a very clear 14-page manual.

M-MASTER

(available for all computers)

The first computer version of the card game that is
favored by members of Mensa, the" high IQ club", is now
offered exclusively by DYNACOMP.

While easy to learn, just as chess is easy to learn, the H igh
IQ game demands a different approach and strategy with
each new hand. I n many ways, the appeal of this game is
the same as the appeal that high-stakes gamblers find in
Old Maid, though the games are not related in any way.
There are two levels of play. At the computer's best
strategy level, it may be truly unbeatable; at the normal
level of play, the human has a fighting chance if he is
sharp enough and willing to take chances.

To our knowledge, this is the first time that the High IQ
favorite has been offered as a computer game, and joins
the broad DYNACOMP library of leading software.

POKER PARTY

(available for all computers)

If you enjoy draw poker, then this is the software package
for you.

POKER PARTY is better classified as a simulation than a
game. As a simulation, POKER PARTY is an excellent (and
inexpensive) tool for learning the subtleties of draw poker.
As a game, it is simply fascinating!

POKER PARTY differs from most microcomputer poker
games in the following two important ways. First, the level
of play engaged by the computer opponents on the whole
is quite high. Second, it is not just a two-handed game (how
often do people play two-handed draw poker in real life?),
but rather seven-handed. The usual rules of draw poker are
followed, including a maximum of three rounds of betting
before the draw (up to five cards), and at most three after.
Aces may be used either high or low in straights, and there
is a wild card.

The six computer players each have a different" personality"
ranging from conservative to risk-taking. You can get to
know your opponents with time, but it will require careful
observation of the betting patterns. Your seating position
changes from game to game. Sometimes you will follow a
bluffer, other times he (she) will follow you.

Spend an evening with POKER PARTY for enjoyment, or
practice for that next money game!

The POKER PARTY package also includes a 6 page manual
describing how to play as well as providing information on
strategies.

Requires 16K of program memory (Atari requires 24K).

SENIOR AIRCRAFT CONTROLLER

(Commodore 64 only)

Simply put, SENIOR AIRCRAFT CONTROLLER (SAC) is
the most realistic aircraft controller simulation available.
It took 2!/i years to develop, and was written by an actual
controller and pilot. It has been extensively tested by
other controllers, pilots, and non-aviators to ensure
accuracy as well as playability.

SAC does not suffer from the limitations apparent in the
many other controller simulations. For example, it in¬
cludes:

• Four different types of aircraft having varying climb/
descent rates and air-speed ranges.

• Weather radar, communications interference.

• Routing via a dozen beacons, holding and specific
heading instructions (not joystick directions).

• Noise abatement procedures, minimum safe
altitudes.

• Six different air-space maps (of increasing difficulty).

• Varying work load, efficiency points.

• A manual describing controller procedures and
techniques.

With SAC you will learn to issue commands using realistic
formats (sorry, no joystick or fire buttons—that's for
arcade games). You will have to plan, anticipate, and
worry. Your involvement will be intense, and the stress
high.

You do not have to understand computers to use SAC,
but you will have to learn many of the skills of an aircraft
controller. The manual is designed to teach you, but you
must also be willing to learn.

A printer is suggested, but optional.

WAR GAMES

THE DYNACOMP BATTLE TRILOGY

Are you a wargamer? Do you like Atari's EASTERN
FRONT? If so, you will be delighted with each game
in DYNACOMP's battle trilogy: WATERLOO 1815,
LEIPZIG 1813 and SHILOH 1862. Each of these
simulations uses standard military symbols and pits
you against a tough computer opponent. Each
program, after compacting and optimizing the code,
is twice as large as the very popular EASTERN
FRONT. In short, both from a graphics and strategy
viewpoint, these games are excellent.

Since many will want the complete set, we offer the
following package price:

BATTLE TRILOGY: Three Cassettes: $42.95

BATTLEFIELD!!!

(available for all computers
except North Star DOS/BASIC)

BATTLEFIELD!!! is actually eight games in one. It is
based on the eight disk war games set originally
distributed by Xitron Systems for the North Star
computer. A year ago DYNACOMP acquired the
publishing rights for this software and for all conver¬
sions to other computers. During the process of
translation we found that the essential features of all
eight games could be combined into one group of
programs which would fit on a single disk. We
named this combination program BATTLEFIELD!!!

BATTLEFIELD!!! is a tactical simulation of war. You
may choose one of eight battle terrains on which to
play. The combatants have armies composed of
both infantry and armor. The aggressor has thirteen
armies, the defender, ten. The terrains include
mountains, swamps, plains, slopes, rough ground
and woods. The game is played by turns. During
each turn a given side can move and shoot with each
army. Then the opportunity switches to the other
side. A particular game can end one of three ways:
Time has run out; the aggressor has gained a chosen
number of victory points (by damaging/destroying
armies); the target has been reached.

Although BATTLEFIELD!!! is best played with two
people, our programmer found that it was also very
interesting to play against yourself. For those inter¬
ested in a game of strategy combined with excite¬
ment, this is a good choice. Requires 48K.

THREAT FORCE

(Atari only)

THREAT FORCE is a battalion-level, one-player
simulation of a hypothetical battle between U.S.
Army forces in Europe and invading Soviet/Warsaw
Pact forces. The player controls the American units
and may choose to defend with either a mechanized
infantry division or an armor division. The THREAT
FORCE, controlled by the computer, is composed of
a motorized rifle division and a Soviet tank division.
The player uses a joystick to direct the movement
and artillery bombardments of friendly units and to
check the attack and defense strengths of enemy
units. To win, the American forces must prevent the
Soviets from capturing the city of Kreigsden. THREAT
FORCE uses the Atari's special capabilities to show
tanks, armor, etc. You design your own level of play
difficulty by modifying the combat strength of each

Wargamers and non-wargamers alike will enjoy
THREAT FORCE. You need not know anything about
wargaming to play this game. The computer will
make all of the necessary calculations and execute
all movement and combat actions; you simply give
the orders. TH REAT FORCE requires strategy, tactics,
and luck. Average playing time is one hour per
battle.

Requires one joystick, 32 K (cassette), 48K (diskette).

ATTACK ON KABUL

(IBM only)

As a Mujahidin Afghan tank commander, your goal is to
recapture the capital city of Kabul from the Soviet forces
using the last battle weary T48 tank left in the
Resistance. You will have to battle your way out of the
mountains and cross the river with your tank to reach
Kabul. Should you succeed in defeating the enemy in
the capital city, you will have a chance to destroy the
Red Army's fuel depot on the outskirts of Kabul, forever
driving the enemy into the hills where they will face the
onslaught of your rebel forces. It will be a fierce tank
battle, but you must succeed. Your countrymen are
counting on you.

SEA WAR

(Atari only)

Quite often the best basis for a new computer

IRONCLADS

(48K CP/M systems only; e.g., Osborne, SuperBrain,
NEC, North Star)

IRONCLADS is a simulation of naval strategy and
tactics between steam and wind driven warships of
the 1860's through 1890's. Although originally
designed for two players, single play against yourself
is possible.

The simulation is very complete and realistic. Each
side consists of a flotilla of ships. Each ship is
characterized by its speed capability, seaworthiness

(e.g., damage level) and fire power. The gunnery is
very nicely modelled in terms of there being four
batteries (forward, aft, port, starboard) on each ship,
with each battery capable of firing different weight
shells and having limited fire arcs. Ships can be
trapped against the coast line or caught in port. You
can even attempt to ram if all else fails.

With IRONCLADS you will gain an appreciation of
the strategy and tactics involved in engaging in sea
battle.

MISSION:

INTERGALACTIC DIPLOMACY

(IBM and CP/M only)

Your mission, should you choose to accept it, is to bring
peace to a war-torn region of the universe. Region W-4,
though remote, is close enough to galactic trade lanes
that wars between planets in this region are beginning
to disrupt intergalactic shipping. As a seasoned inter-
galactic diplomat, you have been offered the assign¬
ment of establishing diplomatic communications within
region W-4, and thus bringing peace to the area.

You will have to explore Region W-4, for no maps are
available. You must decide how to approach each
planetary government for permission to install galactic
communications: Will you try a hard sell (with threats of
Federation reprisals if they are not cooperative), or a
soft sell (with promises of the benefits of peace), or will

you try to bribe local officials? Or, will you just rely on
beaurocratic channels to obtain the needed permits?

Your diplomatic assignment will tax your patience and
persistence to the limit. Can you survive being thrown in
the cargo hold of a spaceship? Can your pride survive
abrupt expulsion from a previously friendly planet?
However, the rewards of diplomatic success are
sweet—you can see your Galactic Credits accumulate,
and the Federation holds out a promise of a planet of
your own to retire to.

Are you a risk taker? Bold strategies might mean quick
success—or might mean ignominious defeat. Each time
you play the game, a new universe, with new planets,
will challenge you to try different strategies.

MANAGEMENT SIMULATOR

(available for all computers)

This program is both an excellent teaching tool, as well as a
stimulating intellectual game. The MANAGEMENT
SIMULATOR (byGiga, Chicago, Illinois) is based on similar
games played at graduate business schools by teams of
managers. The game realistically models the economic
marketplace of the business world.

Each player, or team of players, controls a company which
manufactures three products. The company competes
against other companies, each of which sells three similar
products. Each player attempts to out-perform his
competitors by selecting what he perceives to be. an
optimum operating strategy. This strategy includes setting
the following: selling price, per unit manufacturing costs,
production volumes, marketing and design expenditures,
plant and securities investments, as well as stockholder's
dividends. The most successful firm is the one with the
highest stock price when the simulation ends. The computer
can also compete as a" pacesetting company". This feature
is most useful when playing alone.

The MANAGEMENT SIMULATOR can either be played
on-line or off-line and data from unfinished games can be
saved on disk for continued play at another time. Each
player will be able to study an income statement, a chas-
flow report, a balance sheet, a plant report, various
prod uct feports, past- and projected-busi ness i ndexes, or -
a competition report. It is from this information that the
player ccan make suitable business decisions.

MANAGEMENT SIMULATOR comes with a 9-page in¬
struction manual which includes a sample playing form.

SPECULATION

(TRS-80 only)

DYNACOMP's MANAGEMENT SIMULATOR has
proven to be so popular that we decided to add a
stock market simulation to our product line. Here is
the market you will encounter:

There are thirty three companies grouped within
eleven major industries. The companies encompass
three risk ranges: growth, investment and specu¬
lative. Each player (two to four players) starts with
$15,000 in capital. Companies can merge, go bank¬
rupt, or be taken over (by a player obtaining majority
control). Rumors are given regarding splits, price
changes and merges. There are annual reports, tax
audits, etc.

MASTER THE MARKET

(IBM only)

This is a fast moving stock market game, for 1 to 10
players, that closely simulates real market conditions.
Players buy and sell from a selection of 10 blue-chip
stocks to see who can accumulate the most wealth. The
game uses some exciting graphics, including stock price
bar charts and simulation of the NYSE ticker tape. News
events, randomly selected, affect the day's market

Because the behavior of each of the ten stocks is
randomly and independently generated, no two game
sessions will ever be the same.

MASTER THE MARKET also maintains each player's
portfolio. At the end of a trading day, each player's
portfolio is appraised for net worth, and the player's
performance as an investment manager is ranked with
the other players.

MASTER THE MARKET can be played on either of two
levels: as a regular cash purchase game or at a more
sophisticated level that allows players to buy stock on
margin and sell stock short.

MASTER THE MARKET is also an educational program
for novice investors who are learning how to "play the
market". The simulation is realistic enough to teach
some important lessons before real money is commit¬
ted to the stock market.

Requires 128K. BASIC is not needed.

Price: $29.95 Diskette

When given a choice to run under NBASIC or CP/M and
MBASIC, choose the latter; you will have more free
memory to work in.

YACHT RACE

(Atari only)

YACHT RACE is a tactical game of navigation, sailing
knowledge, and boat-handling skills. Using paddles (no
pun intended) or joysticks, two yachts are sailed around a
triangular course in a race to the finish. To achieve
maximum speed, the skippers use controllers to steer the
yachts and to trim sails according to the direction and
speed of the wind. Hazards include rocks, course marks, a
ferry, the beach, and collision with your opponent's
yacht. Five courses and four degrees of difficulty may be
selected. Compete against your own best time or against
another player for a selected course.

Requires 48K, two joysticks or paddles.

STARBA8E 3.2

(available for all computers)

STARBASE 3.2 is a new and exciting program related to the
classic space simulation many have played on "large"
computers. This version is a significantly enhanced pro¬
gram, is more complex, and is more challenging. It was
written by a visiting Croylin who decided to give his side a
chance. The Empire gets even!

The Croylins have learned from their past experiences.
Their task force is now composed of both light (the old
style) and heavy cruisers. Some of the heavy cruisers have a
proton torpedo deflection device and must be attacked
from their weak side or with lasers. The croylins no longer
wait to be fired on, but may initiate a battle. They also
attack starbases in distant quadrants without warning and
have enough fire power to eventually capturethose bases
unless the Invincible goes to the rescue.

The Croylins now fight battles with a much better strategy.
For example, they move. Sometimes they will move behind
stars and hide. Other times they close in for a close-range
laser attack. Croylin heavy cruisers sometimes start a battle
with low energy blasts, trying to give the impression of a
light cruiser. However, when the Invincible closes in for a
laser kill ... surprise!

Anyone who enjoys Star Trek” simulations must play
STARBASE 3.2.

USA TRIVIA has four play modes. The first two are the
same game with either one or two players. In this mode,
the game resembles popular TV game shows in that the
players are given clues and they have to "BUZZ" to
respond. It employs full-color graphics with each player
represented as an animated character. The object of the
game is to capture as many states as possible by being the
first to identify the correct state from the clues displayed.

The clues presented are drawn randomly from a data
base of information on the disk. The unique two-player
format provides a competitive atmosphere that will keep
the players engaged throughout the game. The single
player will be challenged to increase his or her score.

The third mode makes USA TRIVIA a unique educational
program. I n this game, a single player is given a state name
and is challenged to select the state from the map of the
U.S.A. This is accomplished by controlling an animated
character which can walk anywhere on the screen. The
player uses the character to point to the state selected.

The fourth presents basic facts on each of the states. It is
entertaining to watch as the animated men on the screen
take turns capturing the states one at a time.

You have the ability to regulate the speed of the program.
This makes the program flexible; it can be a fast-moving,
challenging game or a patient tool for teaching important
facts.

USA TRIVIA requires 128K, and a color graphics card. It
works with DOS 1.0 and newer. BASIC is not required.

graphics and sound effects. You may play against the
computer or against another human. The one-player
option sets you against a slew of computer boxers. Your
goal is to fight your way to the top and defeat the champ.

The top ten scores are recorded on the disk. Both the one
and two-player versions have an individual top score
screen.

You may select any one of the several computer boxers
for the fight. These boxers have different characteristics.
You may want a boxer with awesome power, or perhaps
one with blinding speed. Maybe you want a boxer with
fast gloves or a good knockout record. Pick the fighter
with great endurance for those long fights. A complete
description of the computer boxers is given in the boxers'
history (on screen).

You may select the number of rounds (1-15) you wish to
fight.

You are now ready for the big bout. The bell rings and the
crowd roars. Your boxer's fate is in your hands. Will you
duck or guard? Maybe you will run for your life! Try a
couple of fakes? It's up to you.

Wild hair and a crazy look indicate that your boxer has
gone berserk. He is wild. His punches are twice as
devastating. Use this to your advantage but beware of a
berserk opponent.

Now your opponent's eyes are dazed. He looks weary. A
few more punches and he will be down. But the round
ends and the final round begins. Both boxers are tired
and slow. The score is close. Watch out for a surprise
knockout. Every punch counts. Missed punches cost
points. The clock has five seconds left in the fight. You
don't want to face a rematch. The score is even. You have
time for one last punch. Connect and you win—miss and
you lose. Can you do it?

Requires at least one joystick.

HACK AND SLASH is an animated strategy game of
crossbows, axes, greatswords, and other cold-steel
weapons. One or two players can design teams of up to
8 fighters by selecting arms, armor, and fighter attri¬
butes. Teams are then pitted against each other in a
large scrolling arena where animated fighters battle to
the death under joystick control in this simulation of
ancient man-to-man combat.

The selection of weapons and armor, the strength,
dexterity, and I.Q. of the fighters, and the battle tactics
that the players choose, all combine to determine which
fighters will survive. Successful fighters will gain
experience and monetary reward with which to buy
better weapons and armor. Unsuccessful fighters die in
combat and get no reward, but live again to fight in
other battles.

Initial placement options allow players to set up and
test various tactical formations. The sequence of play
alternates between players, with each fighter able to
inspect, ready weapon, move, rest, kneel, and attack.

Average playing time is one hour for a good
intermediate-level battle.

POOL AND BILLIARDS

(Kaypro only)

POOL AND BILLIARDS consists of three graphics
programs for the Kaypro 2, 4, and 10 (1984 and newer):
CAROM BILLIARDS, THREE-CUSHION BILLIARDS,
and POCKET BILLIARDS (POOL).

Carom billiards is also known as French billiards or
canon billiards. It is played with two cue balls and one
colored object ball. Each cue ball is assigned to one of
the players. A player scores one point for each shot
in which his or her cue ball strikes both of the other
balls. The rules for three-cushion billiards are similar to
those of carom billiards, except that the cue ball must
strike at least three sides of the table before striking the
second object ball.

Pocket billiards, or pool, is normally played with one cue
ball and 15 object balls. The players may choose any
number of object balls from 1 to 15, with smaller
numbers of balls providing shorter and faster games. A
player scores one point for each ball driven into a
pocket, unless the cue ball falls into a pocket also. If the
cue ball is pocketed, the player is penalized one point,
and any other balls pocketed on the same shot are
returned to the table.

POOL AND BILLIARDS requires the graphics capa¬
bilities possessed by the Kaypro 10 and the newer
Kaypro 2 and 4 models. Nearly all game functions are
controlled with the arrow keys, the RETURN/ENTER
key, and the ESC key. The arrow keys are used to control
the direction of the cue stick and how hard the cue stick
strikes the cue ball. The arrow keys also move the cue
ball into position for the break shot and after scratching
the cue ball.

POOL AND BILLIARDS can be instructive as well as
entertaining. Each game is an example of a two-
dimensional many-body problem in classical me¬
chanics. All collisions are treated as perfectly elastic
collisions between hard spheres, or between a hard
sphere and a rigid wall. The trajectories of the balls also
resemble the motions of molecules in a gas as described
by molecular dynamics calculations.

For two players (you can play yourself!).

COMMODORE-64 GAMES PACK IV

(Commodore 64 only)

This is a four-game package that has something for
anyone who likes to playgames. In this package there is
an original video game (Suicide Mission), a shoot 'em up
(Arcadia Mania), an adventure game (Rendezvous at
Rafco Castle), and a graphic simulation (Graphic Golf).

Suicide Mission is an original video game that should be
played only by those truly skilled with a joystick. This
game is TOUCH! It has thirty-two different screens of
action with the added plus of being able to change the
screens to what you want with the Landscape Builder
program (also included).

Arcadia Mania is a blast away program that can become
addicting. Are you sick of playing Donkey Kong or
PacMan? Well then, play this game and blast the little
critters into hyperspace.

Rendezvous at Rafco Castle is a lengthy adventure game
that will keep you saying "Whoever wrote this should be
shot!" With a vocabulary in excess of 120 words, you can
do about anything, but just make sure you check out
everything.

Graphic Golf is a simulation that didn't forget a thing.
Trees, bunkers, lakes, wind, club selection, and much
more are included. This isn't your standard pick-a-
direction-type golf game. Depending on your handicap,
the ball could go exactly where you want it to, or it could
go way left or right or even short. You have to overcome
the bad shots just like real golfers do.

APPLE GAMES PACK III, IV and V

(Apple only)

Some time ago DYNACOMP started a search through the
public-domain libraries to find software which could be
offered to DYNACOMP customers as a service. What we
found was largely a group of half-written programs,
beginner exercises, and magazine software. After re¬
viewing many volumes of diskettes, we came up with
over 300K of nice software which, after some reorgan¬
ization and cleaning up, was collected into a three-
diskette set. Each diskette is packed with programs, is
autoboot, and contains a menu from which you may
select the programs on that diskette. These packages are
entertaining and well worth the low price we ask.

Gamas Pack III

STOCKAID III

(IBM only)

STOCKAID III provides the technical market analyst
with the tools to maintain, view, and study the detailed
technical history of up to 64 stocks and the New York
Stock Exchange (NYSE) Index on only one disk. Using
only one disk you can store 250 days of data for each
stock (a full year's worth) and 500 days of data for the
NYSE Index. There is no limit to the number of disks you
can maintain.

For each stock you enter the daily volume, high, low,
and closing prices. A variety of graphic displays of stock
actions and indicators are then available. In addition,
other functions provide all the tools necessary for a
complete technical analysis.

Clear prompts and questions guide you through the
many functions. In general, you respond to prompts
highlighted in green to distinguish them from other
items in the displays which appear in yellow. If you
should make an error (not likely!) an error message
appears in white on a red band at the bottom of the
screen.

STOCKAID III is written to help you avoid mistakes. For
instance, in the Input Multiple Days and Enter Daily
Data functions, the first prompt asks for a date. The
program does a thorough check for a "legal" date. Don't
try to put in February 29 except during a leap year, or a
June 31 anytime. You can't fool STOCKAID III!

Features:

• Ticker symbol, up to 30-character company name.

• Inputs and price relationships are checked for errors
and inconsistancies.

• Display of composite index, advances, declines, new
highs, new lows, volume, etc.

• NYSE Index graphs: advance/decline, trend lines.

• Stock graphs: trends, on-balance volume, relative
action (oscillator), volume bar, point and figure chart.

• Market and stock statistics summary.

As you can see, there is a lot packed into STOCKAID III!
Includes manual, and sample data disk.

Requires 128K of RAM, color graphics card, and one
disk drive.

Price: $39.95 Two Diskettes

EXCERPTS
from a review of
BUYSEL

(by Brian Greiner, Software Now!, April 1985)

"The manual consists of thirty-five pages ... It is well
written, and explains every aspect of the program fairly
completely. One section I particularly appreciated, was a
'walk-through' of all the'various features using sample
data files to show how the program worked. The manual
explains in detail the parameters used by each trading
method, and gives s,ome detailed background informa¬
tion for each method. There is also a brief bibliography of
books the program's author found useful.

In use, Buysel is rather a lot of fun.... I used the supplied
data files to analyze a sample stock and commodity with
no problem. ... Buysel is useful not only for picking the
best investment strategy for a particular stock, but also
useful for weeding out the dogs.... The program seems
reasonably crash-proof and easy to use.

Overall, Buysel seems like a useful tool for people inter¬
ested in the stock market. It offers the user a number of
different trading methods to choose from, and is fairly
simple to use.

HOME APPRAISER

(CP/M only)

HOME APPRAISER is designed to estimate potential
market value of real property. It is intended primarily for
individual homeowners and prospective home buyers. It
allows you to approximate the effects of various physical,
economic, and territorial factors which have some degree
of impact on the overall value of your property. You
supply selected information about the house (or condo)
and the computer provides a depreciated value and a
"bottom line" estimate of projected market value.

Multiple data files corresponding to numerous separate
buildings or tracts of land can be stored and recalled for
further analysis. Additional user-specified parameters
allow numerical rating of the overall quality of the sur¬
rounding neighborhood, including the relative conven¬
ience of shopping, schools, etc. The program also takes
into account several local and regional economic factors
which affect property values and "buying power" in a
general way. Fully documented instructions are included.
No printer or special graphics capabilities are required.

As an aid in tracking the changing value of your largest
investment, your home, HOME APPRAISER offers the
appeal, simplicity, and low cost not found in most busi¬
ness-oriented real estate packages. The prospective
home buyer can also benefit by using HOME APPRAISER
as a tool to estimate and compare the values of several
properties.

SOME COMMENTS ON
IBM “COMPATIBLES”

Our guess is that there will eventually be a law requiring
manufacturers of IBM "compatible" computers to
specify how incompatible their computers really are.
Maybe a legal case will extend "truth in advertising" to
computers. (Actually, Commodore has been bitten hard
by this One!) For example, so called IBM "compatible"
computers with Vh" disk drives simply will not accept
5V«" disks! Also, stating that a computer is 95%
compatible is frightening; does that mean that 5% of
each program won't work?

We had an experience with a local dealer which
perhaps reflects what many shoppers face today. The
dealer first claimed that his machine was 100% IBM
compatible. After some grilling he conceded that some
software wouldn't run (he didn't know why) and some
plug-in boards were not compatible ("You see, IBM
made a mistake in the cables for their disk drives. We
did it the correct way," he said.) If we hadn't known to
ask specific questions about compatibility, we wouldn't
have found out about the exceptions. Good grief!

What is this discussion leading up to? Simply the
following: When you call DYNACOMP to place an
order and you are told that the IBM software you want
will not work on your "compatible", please believe us! If
you are told that you may need special "ASCII"
versions, again, please believe us. Every day we
encounter people who have discovered problems with
their IBM "compatibles". Please help us help you order
the right software.

We also suggest that if you purchase an IBM "compat¬
ible", and it is advertised to be compatible, and you find
that it actually isn't, complain about false advertising!

DISKETTE RECOMMENDATIONS

We have noticed that some brands of diskettes work
better than others, seemingly independent of the manu¬
facturer's advertising or pricing (whethertheyare guaran¬
teed for 90 days, one year, or five years apparently makes
no difference in the failure rate). All we can say is that
DYNACOMP uses (and sells) only those diskettes which
it has found to be most reliable, given some cost con¬
straints. There are some brands which are very high
quality and very expensive, but the difference in per¬
ceived reliability may not be worth the difference in
price.

However, we do not recommend that single-sided disk-
etts be used (in single-sided drives) on the second side by
cutting an extra notch. Although many people have done
this with some success, they are taking a chance. The
problem is not "print through"; the diskette is more than
thick enough to prevent that. The problem is not using a
side that has not been verified; you caj) do that verifica¬
tion yourself. The problem is the direction of disk rota¬
tion. When you remove the diskette and flip it over, you
reverse the direction of rotation. There two things wrong
with doing this.

First, the diskettes are polished by the manufacturer in
one direction, the direction used in your drive in the
normal mode. When the diskette is flipped, it runs the
opposite way. Consider your hand to be the head, and a
cat to be the diskette. When you brush the cat one way,
your hand glides over the fur smoothly. When you brush
it in the opposite direction, the fur fluffs up and there is
more resistance. Simply put, you run the danger of
shortening the life of the "good side" of your diskette, as
well as increasing head abrasion.

Second, the inside of the diskette contains a porous liner
which picks up and traps dirt. Flipping the disk over and
running it "backwards" may dislodge some of the debris,
which may pass under the head or stick to it

Therefore, although this is an unpopular view, DYNA¬
COMP recommends that you do not try to save money by
using the back side' of the diskettes in single-sided disk
drives. Diskettes are inexpensive enough (see DYNA-
COMP's prices!) that the risk is not worth the anticipated
savings.

PUBLIC DOMAIN T COMMODORE-64

CP/M and IBM DIRECTORY

COMMODORE 64 PUBLIC DOMAIN

(C-64 and compatibles only)

Although there are literally millions of Commodore 64
computers in the world, the amount, of public domain
software available for this machine is very limited
(compared with CP/M, Apple, Atari, and IBM). The
reason for this is probably the extreme slowness of the
1541 disk drive; making a copy of a C-64 disk takes 4 to
20 times longer on a 1541 than on an IBM drive (and
the IBM disk holds more!). Using the Butterfield
COPY/ALL program, some disks (full ones) take 40
minutes to copy! This greatly limits the ability of user
groups to distribute their libraries. They simply cannot
afford the time to make thousands of copies, or the
money for high-speed duplicating equipment.

DYNACOMP is going to partially fill the void with the
following collection. These disks are for sale only. We
decided not to offer the collection for rental. The wear
on disks in the 1541 drives is so great that rental disks
would not hold up well enough.

The copying fees below reflect both the extra cost of
double-density high-quality disks (the 1541 is sensitive
to disk quality) and extra effort in disk duplication.

DYNACOMP CP/M and IBM
PUBLIC DOMAIN DIRECTORY

One of the problems with providing over 1,000 volumes
of public-domain software is that it is impossible to
adequately describe the contents of each volume in the
DYNACOMP catalog. Also, since DYNACOMP's prices
are so low, we cannot afford to have our order
department spend the time to describe the contents of
each volume over the phone (even if they could without
becoming confused by the sheer number of programs!)

In an attempt to help improve the situation and provide
you with more information, DYNACOMP has prepared
a 486-page public-domain software directory. This
directory lists over 700 volumes (over 12,000 files!),
with a one-line description (in most cases) for each file.

We thought about distributing this information on disks
but found that (1) it was cheaper to print the
information and (2) the hard-copy format is much easier
to use.

This directory covers the following public-domain soft¬
ware sets:

IBM PC-BLUE, Volumes 1-131

• IBM PC-SIG, Volumes 1-370

• IBM PC-GREEN, Volumes 1-42

• CP/M User's Group, Volumes 1-92

• SIG/M (CP/M), Volumes 1-209

• PCNET (CP/M), Volumes 1-34

• KUG (Kaypro CP/M), Volumes 1-25

• Apple CP/M, Volumes 1-25

• PASCAL/Z, Volumes 1-22

If you are interested in building an IBM or CP/M public-
domain library, or just finding out what is available, you
will find this directory indispensable. Comes punched
for a standard 3-ring binder.

PC-SIG SOURCE NOTICE

NOTE: The PC-SIG public domain collection was not
developed by DYNACOMP but by a company of the
same name. They have not authorized DYNACOMP to
distribute this software because DYNACOMP's low
prices have cut into their business. Needless to say, the
-PC-SIG company is annoyed with DYNACOMP._

PUBLIC DOM AIM SOFTWARE
FOR THE IBM PC

(IBM only)

Here is a large collection of public domain diskettes for
the IBM PC which you may either purchase or rent from
DYNACOMP. Some of the diskettes are in the "freeware"
category; the author encourages you to make a donation
to him or her if you like the program. In any case, these
diskettes contain a great deal of software which you may
be able to use directly or can modify to suit your needs.
These are user-donated programs and are not necessarily
as nicely done as the corresponding commercial pro¬
grams (i.e., no guarantees!).

The format used is MS DOS and PC DOS 1.0/2.0/3.0 and
one side/two side compatible.

You may purchase individual diskettes, purchase the col¬
lection in parts, or rent it in parts according to the
following schedule:

money order, or certified check.

For those choosing the 10-day rental approach, the
following conditions apply:

1. Only Master Card, Visa, and American Express will be
accepted.

2. There is a $10 per day late charge if the library is not
returned on time. Your charge account will be billed for
each day the library is overdue, up to the purchase price
of the library. Please appreciate the need to have the
library returned on time (so that it can be sent promptly
to the next renter).

Sorry, these diskettes may not be included in. or used
toward DYNACOMP's 10%-20% quantity discounts.

PUBLIC DOMAIN SOFTWARE
FOR THE IBM PC

(IBM only)

As with the PC-SIG library (described elsewhere), DYNA-
COMP is making available some very nice public-domain
software at a price which basically just covers our costs.

You may either rent the entire collection for 10 days
($99.95), purchase it ($399.95), or purchase selected
diskettes ($5.95 each). The format used is single-sided
MS DOS and PC DOS 1.0/2.0/3.0 one sided/two sided
compatible. We have not included the entire collection
because of overlaps with the PC-SIG library, and because
some of the diskettes require an 8-bit 8080 micro¬
processor (it is not clear why they are in the library at all!)

If you choose to rent this library, the same restrictions
apply as for renting the PC-SIG library; the late charge is
$10.00 per day. Individual diskettes cannot be rented
and these diskettes do not count toward volume
discounts.

Price: $399.95 - Purchase of complete collection

$ 99.95 - 10-day rental (plus $10/day late charge)
$ 5.95 - per individual diskette

You will find these prices to be lower than those available
elsewhere, and our speed of delivery is impressive.

WHEN ORDERING
PUBLIC DOMAIN DISKS ...

Please do not make the following mistake. If you see a
public domain listing such as "171-174 Supersomething
Software Library", this is not one volume. The listing
refers to four volumes (171, 172, 173, and 174) of
software. If the price is S3.95 per volume, the price for
our example (171-174) is four times S3.95 plus shipping
and handling.

APPLE PUBLIC DOMAIN SOFTWARE

(Apple only)

The DYNACOMP quest for public domain software con¬
tinues! This time we've uncovered a library of 121 disk¬
ettes. From these we selected 50 for inclusion in the
DYNACOMP catalog. These diskettes are super bargains
for the price. A word of caution, however: these pro¬
grams are not supported, and are not necessarily of
commercial quality. If a diskette has a read error, we will
replace it free of charge. Otherwise, no returns. We
simply can't afford to support this software at the price
we charge (basically a small copying fee plus the cost of
the diskette). Also, no other discounts apply other than
those given below. All diskettes are copied on one side
only, but there is a lot on that side!

Price: S 3.95 each (1-4 diskettes)

KAYPRO USER'S GROUP

CP/M PUBLIC DOMAIN
COLLECTION #1

(CP/M only)

This is the first of DYNACOMP's CP/M public domain
offerings. We chose to start with this particular nine-disk
set because of a unique situation: documentation. Most
of the programs in this set are described in a book
published by People Talk Associates (see below). A
word of caution, however. The People Talk book is vital
(you probably will not be able to use the software
without it), but it falls short of what would be expected
from "commercial" documentation.

These disks contain both machine language and BASIC
programs. You must have an 8080 or Z-80 micro¬
processor (usually the case) and Microsoft BASIC. These
disks can not be applied toward DYNACOMP's 10%-
20% quantity discounts. Be sure to state the disk
number (e.g. CP/M-3) when ordering.

Price: $17.95 book only
$ 4.95 per disk
$39.95 for 9-disk set
$53.95 for 9-disk set and book

CP/M UG PUBLIC DOMAIN

(CP/M only)

This is the well-known CP/M Users' Group Library which
has formed the backbone of public domain software for
the CP/M environment. Originally this library was
available only on 8" disks. Now, through DYNACOMP,
it is available not only in the 8" IBM 3740 format, but
also in all of the standard and special CP/M formats
handled by DYNACOMP (including Apple Z-80 CP/M);
see below.

Requirements:

1) A CP/M format which DYNACOMP covers.

2) An 8080/Z-80 CPU for the machine language
programs.

3) Some knowledge of how to load, list, etc., files.
There are no printed manuals. The only documen¬
tation is on the disks themselves.

DYNACOMP's prices basically reflect the costs of the
disk(s), and the copying and inventory expenses. The
single-sided single-density formats cost the most be¬
cause up to four SSSD diskets are required to hold the
same contents ("one volume") as one 8" disk; DYNA¬
COMP copies on only one side of single-sided diskettes
for the sake of reliability and reduced head wear (yours
and ours; other companies copy on both sides of single¬
sided disks. This results in much frustration when BDOS
errors occur!).

The library may be purchased in part or as a whole, or
rented as a whole, acggrding to the schedule below.
DYNACOMP will replace defective disks, but does not
warrant the software on the disks (we did not write it!).
These disks and diskettes may not be used in or toward
DYNACOMP's 10%-20% quantity discounts.

Note: DYNACOMP maintains a large stock and ships
within 48 hours; other public domain sources are
exceedingly slow!

DYNACOMP's "standard" 5V«-inch formats are: KAYPRO, OSBORNE, and MORROW. See the SPECIAL ORDER FORMATS box
on the inside-front cover of this catalog for availability. Not available for North Star. The 8-inch IBM 3740 format is treated as
equivalent to 5!A-inch DSDD; use the DSDD prices.

**Rental is for 14 days. Master Card, Visa, or American Express charge cards only. If .the set is not returned in 14 days, you will
be charged $10.00 per day extra up to the purchase price. Remember, others are waiting to rent the library!

Make sure that you specify.

1) Your machine make and model.

2) Whether the diskette(s) are to be single or
double sided, single or double density. Eight-inch
CP/M disks come in IBM 3740 format only.

3) The complete stock number (e.g., CP/M UG#3).

HAVE YOU EVER WONDERED...?

Why does DYNACOMP use un-retouched black-and-
white computer-screen photographs instead of fancy
four-color art work to "push" its products?

Open a computer magazine and just look at the art work.
Do it as an experiment. — Nice copy, isn't it? However,
how much of this art work actually conveys real infor¬
mation about the product? How much of it leads you to
expect things (e.g. graphics beyond the machine's capa¬
bility, a beautiful secretary, fantasy, etc.) that are not
really in the products? DYNACOMP's advertisements
and catalog descriptions are simple and factual. How¬
ever, even we have trouble restraining our advertising
department on some of our products!

ATARI

PUBLIC DOMAIN COLLECTION #2

(Atari only)

We learn from experience. We introduced the ANTIC
Public Domain collection in Catalog Number 26 and it
was nicely received. That prompted us to search for
additional material of the same type. This second collec¬
tion of 38 disks is another "best buy". Each diskette is
nearly full, and the programs are good to excellent.
Individual diskettes may be purchased for $7.95 each, or
the entire collection may be obtained for $199.95. Sorry,
these diskettes may not be used toward DYNACOMP's
10%-20% quantity discounts. Remember to order by
diskette number (e.g., PD #7). M/L = Machine Language.

THE ANTIC®

PUBLIC-DOMAIN SOFTWARE
LIBRARY

(Atari only)

Good news for Atari and Atari XL owners!

DYNACOMP now distributes the public-domain soft¬
ware library compiled by ANTIC® magazine. These disk¬
ettes contain classic computer programs translated to the
Atari (with enhancements) as well as material written
specially for that machine.

The library presently consists of well filled diskettes
covering games, utilities, graphics, communications, and
music. ANTIC® distributes these diskettes for $10 each.
DYNACOMP, because of its higher volume/overhead
ratio, offers them for only $7.95 each, an exceptional
value. Also, you may purchase collections of these disk¬
ettes at substantial discounts (less than half ANTIC'S
price):

_ Collect ion _ Price

A: ANT- 1 to ANT-27 $129.95

B: ANT-28 to ANT-55 $129.95

C: ANT- 1 to ANT-55 $249.95

Sorry, these items cannot be used towards DYNA-
COMP's 10% - 20% quantity discounts.

Be sure to carefully identify which diskettes you want (for
example, ANT-7). No manuals are included. The pro¬
grams are generally self-prompting or magazine refer¬
ences are given.

Note that DYNACOMP's numbering system is not en¬
tirely the same as that used by ANTIC® magazine. Com¬
pare by contents.

REWARD!

One of the more curious debates appearing in the
computer magazines (and elsewhere) is whether or not
violating the copyright laws by copying software is justi¬
fied or not. Those who think that such stealing is accept¬
able have all sorts of arguments aimed at rationalizing
their behavior.

Quite frankly, we believe that it is pointless pursuing
philosophical discussions in this area. Copyright violators
should instead be given the opportunity to tell their story
to a judge! That way they would soon learn "which way is
up".

DYNACOMP's approach is simple. We will give a 25%
reward to anyone who supplies us sufficient evidence to
prosecute a copyright infringer. This reward will be based
on the cash damage settlement awarded DYNACOMP,
namely the lost sales damages and the punitive damages
(These are the big ones. The fines are large!). The court
cost and attorney fee award is not included; it will be
used to coverOYNACOMP's legal expenses.

DYN ACOM P and the F Bl (we have been working with the
Rochester FBI office) will make every effort to keep your
identity confidential. If you would prefer to contact the
FBI directly, direct your information to Mr. Gil Cooper,
Federal Bureau of Investigation, 100 State Street, Room
300, Rochester, NY 14614.

Incidentally, ignorance of the copyright law is not a good
defense; a school district recently paid over $300,000 to
find that out!

SUPPLIES and HARDWARE

DYNACOMP is one of the world’s largest distributors of micro¬
computer software. As such, we purchase supplies and hardware
in large quantities and at greatly reduced prices. Let DYNACOMP
become your source for the highest quality supplies at the lowest
prices available.

5V4” DISK DRIVE
HEAD CLEANING KIT

If you have used your disk drive extensively, and once
in a while you get a disk I/O error, then it is possible*
that your disk drive head may be getting dirty. If so, you
can either disassemble your drive and clean the head
directly (we do this for our 8-inch drives), or use a head
cleaner diskette (as we do for our 5Vi" drives).

Although it is said that "dry" cleaning works as well as
"wet", it is our opinion that the wet method offers less
chance for abrasion. The kit carried by DYNACOMP
(and used in our lab) comes with a double-sided
cleaning disk and a bottle of special solvent. Just put a
few drops of solvent on the cleaning disk and "read" the
disk for 15 to 30 seconds. You may be surprised how
much dirt may come off!

Price: $7.95 per kit

* There are several other possible reasons for a disk I/O
error. If you do not have much mileage on your drive,
the most likely source of the problem is the diskette
itself. Another potential cause is head misalignment
(not easily fixed without .test equipment).

We have also encountered several cases in which the
pressure pad (on single-sided drives) has worn out. This
is easy to check by eye and simple to replace (proceed
carefully!) You really have to put a lot of hours in on a
drive to wear out a pressure pad. However, low grade
(not micro-smooth or mirror-finish) diskettes greatly
accelerate this failure.

MAILING LABELS

We recently had the opportunity to visit a Radio Shack
store and were amazed at some of the prices (high!).
One particularly high-priced item was tractor-feed one-
up (15/16" X Vh” by 12 per fan fold) mailing labels.
DYNACOMP uses the same labels for its catalog
mailings, and usually we purchase a few hundred
thousand at a time. Therefore, DYNACOMP gets a very
good volume price break and can pass some of those
savings on to you.

Price: $3.95/1,000 (1,000 to 4,000)
$3.49/1,000 (5,000 and up)

Minimum order. 1,000 labels

Orders must be in multiples of 1,000 labels.

Shipping is $3.50 per order, independent of quantity.

CARDBOARD MAILERS

If you send disks or diskettes through the mail, you
have had two choices. You could spend time to Cut up
cardboard boxes to make a protective sandwich for
your floppy, or you could buy a mailer for from 75<t to
$1.50 (or more).

Now DYNACOMP offers a third and much less ex¬
pensive solution to your mailing problem. For five
years DYNACOMP has been shipping disks and disk¬
ettes through the U. S. mail using cardboard boxes
made especially for DYNACOMP. During that time,
only one diskette has been damaged, and that was

under curious conditions (a determined mail carrier
somehow managed to fold the box, probably using
both hands and a foot). Now DYNACOMP offers these
same mailers to its customers at quantity savings.

Each box comes unfolded (flat), cut to shape, and
scored at the folds. You simply fold it up and tape it. We
use a good grade of stiff cardboard and the construc¬
tion is exceptionally strong.

The 5W' diskette mailers hold one, two, or three disk¬
ettes. The 8" disk mailers have three crease positions
and can accommodate from one to six disks.

VOTRAX SPEECH SYNTHESIZER

APPLESAVER* FAN

Quite frankly, most Apple ils do not need a fan to keep
them cool. They run warm, but not so hot as to create a
problem. However, if you also have extra boards plugged
in, or are doing a significant amount of disk access (the
disk drives are powered by the computer) the insides of
your Apple 11 can heat up. A rule of thumb (the Arrhenius
relation) predicts that the component failure rate should
roughly double for each 10 F increase in temperature.
Therefore it pays to keep your computer cool.

The APPLESAVER” FAN does just that. It attaches to the
side of your Apple using two plastic clips which slip into
the air slots. Air is drawn across the inside back of the
machine. The fan itself is very quiet, though effective.
Also, the back of the unit contains two grounded AC
sockets for plugging in your computer, monitor, etc. The
front has a power switch (Apple type) and indicator lamp.
Therefore you need only flip the fan switch to turn on
your^ystem as well as the fan.

the APPLESAVER” FAN is very well built. The fan itself is
of high quality, and the molded plastic housing is of the
same material (and color) as the beige apple case. We use
these units ourselves.

Includes surge protection.

Now for the really good news. Similar Apple fan units
have been advertised nationally for $89.95. DYNA-
COMP's price is only $49.95! Comparison shop, and you
will find our price to be exceptionally low.

Price: $49.95

Dealer inquiries invited. We're going for volume on this
one!

PHONE FORWARD
AUTOMATIC CALL FORWARDER

PHONE FORWARD is an easy-to-install and easy-to-use
phone accessory which allows you to re-direct incoming
phone calls. For example, you may go to your cottage for
a visit and would like to have your home phone calls
transferred there. Or, you may want to redirect calls
from home to your office; or you may have changed
office locations.

You must have a two-line phone with standard two-line
modular jacks (or adaptors) to use PHONE FORWARD.
It can be either dial or touch-tone service. PHONE
FORWARD is simply plugged in. Using the keyboard on
the PHONE FORWARD you enter the phone number
(including long-distance codes) to be dialed. Then, any
call coming in on one line will be re-dialed and sent out
on the other line.

DYNACOMP first came upon PHONE FORWARD in the
Markline catalog (for $129.95). We got three and used
them for more than six months to transfer calls from our
Rochester offices to our new offices in Webster. We
were very pleased with the results, especially con¬
sidering how expensive the alternatives were (phone
company transfer service charges and other devices).

Limitations: a) You must type in the number; you cannot
set the re-dial number from a remote location, b) If the
phone traffic is heavy (many calls on both lines) and the
phone service is poor, and you have an automatic
search system, then it is best to have a line installed just
for the re-dialed outgoing calls, c) If the re-dialed
number is in another exchange, there may be some
volume loss in the transmission.

Conclusion: We love it—and we think that it has a good
price/performance ratio, too.

SURGE PROTECTOR OUTLET STRIP

This is one of those items you regret not having after a
spike has glitched your computer.

We picked this particular outlet strip because of some
interesting features. First, it has six outlets,'each surge
protected. Four of the six are switched; the other two
are not. For example, the computer, printer, etc., could
be plugged into the switched outlets, and your clock
and desk lamp could be plugged into the unswitched
outlets. You could then flip the computer system off
without turning off the clock and desk lamp.

The switch is an illuminated rocker type, and the outlet
strip contains a plug replaceable fuse (standard auto¬
mobile type; 10 amps).

Both the neutral and “hot” lines have varistors to
ground. These varistors are meant to catch spikes which
exceed 225 VDC. They will divert 50 amps at 440 volts
for 20 milliseconds or 2500 amps for 20 microseconds.
The two types of failures which surge-protector strips
do not guard against are long-term voltage level changes
(over voltage and drops; autotransformers are needed
for these) and power failures.

The device is constructed with an in-line outlet pattern,
heavy gauge metal ('painted gray), and has a 6-foot line
cord.

COMPUTER CLOCK

The COMPUTER CLOCK is a cute little (1%" high)
quartz crystal controlled LCD clock resembling an
Apple II with a large screen monitor on top. It comes
with a battery which can be expected to last more than
a year. The battery can be reached by pulling out the
detachable front screen. Besides being fun to own, it
also makes a great gift for the computerist who has
everything, or for the forgotten spouse. We get these in
large quantities so we can offer you a really good price.

THE VOTRAX

PERSONAL SPEECH SYSTEM
(or DYNACOMP VOTRAX OFFER #2)

Two years ago DYNACOMP advertised and sold the
VOTRAX TYPE 'N' TALK speech synthesizer. We also
developed several programs for the unit. Sales initially
were good. However, competition quickly built in the
form of less expensive speech synthesizers, in particular,
the VOICE BOX by the Alien Croup. We examined these
other units and decided not to carry them (even though
they were priced much lower than the TYPE 'N' TALK)
because of quality differences. Quite simply, they looked
like they were made in someone's garage. Also, they
relied heavily on software in the computer to do the
brunt of the synthesis work.

Faced with the choice of carrying a high quality product at
a high price or a lower priced product which did not
please us, we decided todrop speech synthesis hardware
altogether — until now.

VOTRAX now has a new synthesizer which does every¬
thing the TYPE 'N' TALK did, and much more. After testing
the new unit, we are using one ourselves at DYNACOMP.
Here are some of the uses we see:

• A programmingaidforthe blind. The blind person can
hear what is typed on the computer's keyboard.

• A programmed telephone response system. Using a
Touch Tone decoder, a human can respond to computer
generated questions over the phone; an order taking
system.

• An order placing system. Push the buttons on the cash
register and the order is "spoken" in the kitchen.

• A printer buffer.

• A parallel/serial or serial/parallel converter.

Hooking up a new VOTRAX Personal Speech System is
very easy. First, the speaker is contained within the unit
(there is also an external jack for another speaker or AUX
input). Second, you can connect to the computer either
through an RS 232 (DB-25) serial connector, or through a
(Centronics) parallel connector. If you can connect a
printer to your computer, you can hook up the VOTRAX.

The manual clearly spells out how to hook the system up.
We ignored the manual and simply plugged it into an RS
232 port. We weren't surprised when the VOTRAX an¬
nounced itself, but we were taken back a little when it
told us that we had connected it incorrectly! The
VOTRAX has a repertoire of error messages to help you
set it up and operate it. In this case, we had to switch lines
2 and 3 in the DB-25 connector to get it to respond
correctly.

There are many ways to use the VOTRAX. To appreciate
the many possible uses, a brief hardware description is
useful.

You may choose to send information to the VOTRAX
either through the serial or parallel ports. If you choose to
use the serial port, you may set switches to determine the
baud, parity, hardware (RTS/CTS) or software (X-ON/X-
OFF) handshaking, etc. You can override these by send¬
ing particular commands to the unit also. The input is
buffered (3,500 characters) so that you can quickly (e.g.,
9,600 baud) send information to the VOTRAX and have
the computer go on about other business while the
VOTRAX is speaking. However, the unit echoes back
what it is speaking through both the serial and parallel
ports. Since you can adjust the speech rate, you have
control over the echo speed. Thus you can connect a
printer up and use the VOTRAX also as a buffer (spooler).
Or you can do serial/parallel or parallel/serial conversion.

VOTRAX combined a synthesizer with a Z80 micro¬
processor and created an interesting computer! They
also included some very interesting features in the in¬
ternal ROM which supervises this CPU. For example, you
can set the time in the VOTRAX and have it say the time

on cue, or automatically (every 15 minutes). You can also
program in alarms and cues!

Of course there is a self-test mode (it talks as it tests),
volume control, chime, etc. Now we come to the speech
(and music ) synthesis.

There are two basic speech modes: text and phonetic.
You may simply send text to the VOTRAX just as you
would to a printer. The VOTRAX is pretty smart and will
do a fairly good job of pronouncing it. For example, this
catalog description could be sent directly to the VOTRAX
with very good results.

In the phonetic modeyou can send sound constructions
made of phonemes. These can be directly mixed with
text-mode speech. For example, you might find the text
mode pronunciation of hors d'oeuvre to be not very
good. Therefore the phonetic construction might be
useful. Included in the package is a 1,400-word diction¬
ary having phonetic equivalents. Text and phonetic
pronunciation may be mixed.

You may also control various characteristics of the speech
by simple commands sent out with the text.

For example:

Amplitude fade: (a Aar

a=master audio level (0-F)
f=fade rate (0-F)

Speech Rate: (a Rr (r=0-F)

Voice mode: <& Vm
m=0 standard
m=2 tones off
m=4 tones on

Inflection: (a- i (i=0-7)

Naturally, when the unit is turned on, default values are
chosen; you do not have to set any values unless you want
to. The same is true for the music and sound-effects
mode.

The basic music tone command controls the channel
(there are three), note (Cl through B8), duration (in
tempo units), hold (in tempo units), amplitude, and glide.
You may also control the envelope for each note in the
following terms: channel, attack rate, decay rate, sustain
level, and release rate. You may also add noise and define
the tempo. In other words, you can do a fairly complete
job of music synthesis. In addition, you can combine the
speech and music modes.

The thing that we found very interesting and appealing is
that the unit is not only capable of very complicated
speech and music synthesis, but is also very easy to use;
you can choose your own level of involvement.

The VOTRAX PERSONAL SPEECH SYSTEM is well built
(e.g., the case is cast aluminum) and comes complete
with a factory warranty, clear manual, and quick ref¬
erence card.

Suggested list is $399.95. DYNACOMP's price is
$329.95. Price does not include cables.

MAGIC-STAT™

COMPUTER THERMOSTAT

THE STORY

The story behind DYNACOMP's getting involved with
this product is worth telling.

Traditionally, DYNACOMP's president has had low prior¬
ity when it came to allocating office space. Whenever
DYNACOMP needed more space for production, com¬
puters, supplies, etc., it expanded into (and through) his
office. The movers would be called and he would move to
some less vital area. Finally, the next move was to the
parking lot!

To solve the space problem, a separate office was built
(ground up) for the president. The design, inside and out,
was his own. When it came to the thermostat for the
heating system, he was going to use a standard Honey¬
well setback thermostat, the Chronotherm™. However,
the one in his home had just broken and, as a result of that
unhappy experience, he decided to look more carefully
before buying one for the office.

DYNACOMP's president remembered an advertisment
for a computerized thermostat from JS&A. He found the
same thermostat in the Markline catalog, and purchased
it. It arrived. He read the instructions. He installed and
programmed it. It was great!

Then he proposed to DYNACOMP's head of marketing
that DYNACOMP should carry it. The response was
enthusiastic.

As it turns out, the president of Quad Six, Inc., the
manufacturer of MAGIC-STAT™, is a DYNACOMP fan,
having purchased several DYNACOMP products in the
past. Both presidents thought it would be a great idea to
put MAGIC-STAT™ into the DYNACOMP catalog. So,
here it is.

THE PRODUCT

Forget the claims made by JS&A, Markline and the manu¬
facturer's literature. Here are the strengths and weak¬
nesses of MAGIC-STAT™.

The Strengths: The MAGIC-STAT™ keeps track of time.

During the course of a day you may
switch the device to LEARN, set the temperature to what
you want it to be at that time, and switch back to AUTO.
The next day the computer will figure out when to turn
on the heat so that the temperature will come up to the
set point at the desired time (more about this later). You
may have six different set points each day. Each day in
the week may have the same set points (default) or
different if you wish. This flexibility is great for the
weekends. You may also manually override the set point
control by simply switching to MANUAL and setting the
new temperature. Switching back to AUTO restores the
program control at the next set point in time.

The Weaknesses: You must be around to switch the
thermostat to LEARN mode and set
the temperature. For example, if you want it to be warm
when you get home at 5:30 PM, you must come home toa
cold house one day and set the control. The next day it
will be warm at 5:30 p.m. With this thermostat you
program as you go through the day. This is the only
weakness we see in the operation of MAGIC-STAT™.

MAGIC STAT 3000

MAGIC STAT 3000 is a more-expensive version of
MAGIC STAT. It is basically the same device, but with
the disadvantage, discussed above, remedied. MAGIC
STAT 3000 can be programmed very much like a digital
watch. It has an LCD (liquid-crystal display) which
shows the temperature and time information. Other¬
wise, its specifications and performance are identical to
MAGIC STAT.

EXTRA ENEGRY SAVINGS AND COMFORT

Here is where the power of the computer really comes to
play. As the outside temperature changes, the heat must
come on earlier or later to make the inside transition from
cool to warm. What this means for conventional thermo¬
stats is that you have to set the thermostat toturn on extra
early in the morning to handle those really cold winter
nights. But then it comes on too early on the warmer
mornings and you are roasted out of bed! MAGIC-STAT™
is clever. While operating in the “cool" mode, it tracks
the response of your heating system and figures out when
the heat should be turned on in order to reach the
desired temperature. It is continually learning and
adapting! It does not have to be adjusted for the
“advance". There are no adjustments. It is automatic.
(Note: when going from warm to cool, the temperature is
maintained until the cool set point is reached, then it
drops to the new level.)

The computer allows:

1. Easier installation - no adjustments.

2. Much more comfortable control - the tempera¬
ture reaches its set point at the right time.

3. Since the heat does not come on too early, there
is an energy savings over conventional set-back
thermostats — about 5% (you can easily pay for
the unit with these savings.)

THE WARRANTY

MAGIC-STAT™ is a product which is not only great, but
also reliable. It comes with a three year “limited
warranty" relating to malfunctions.

In short, DYNACOMP found MAGIC-STAT™ to be a great
product through personal experience. We are sure you
will like it also.

DYNACOMP’s WARRANTY

MAGNETICALLY DEFECTIVE MERCHANDISE

If, within 30 days of your purchase, you find the DYNACOMP cassette/diskette/disk to be
mechanically or magnetically defective, you may return the original cassette/diskette/disk
to yourdealer (if you purchased there) or directly to DYNACOMPfor replacement. If the fault
is due to an original defect in materials or workmanship, DYNACOMP will replace the
cassette/diskette/disk free of charge, postpaid.

If, within one year of purchase, you have in any way magnetically damaged the cassette/
diskette/disk, DYNACOMP will replace it for a nominal recopying charge of $5.00 plus
$3.50 for shipping and handling. If you have physically damaged it, there will be an
additional nominal charge for replacing the media. See the instructions below regarding
what and how to ship to DYNACOMP.

UNSUITABLE MERCHANDISE

The vast majority of software companies do not warrant the suitability of their software.
We are different. DYNACOMP has gone to great lengths (literally!) to describe its
products in the DYNACOMP catalog accurately and in sufficient detail to ensure that the
customer knows what he or she is purchasing. However, if you purchase a DYNACOMP
product and have a problem or are dissatisfied with it, here is what you should do:

• Contact DYNACOMP. You may do this by writing to DYNACOMP directly or by calling
one of the technical service lines: (716) 671-6160 or (716) 671-6167. Problems get
first priority in the technical support group and they will do whatever they can to help
you. Usually the problem turns out to be a bad cassette/diskette/disk, or misunder¬
standing with respect to the documentation, and is easily remedied.

• If a refund is in order, you will be sent a Copyright Infringement Agreement which is to
be signed and included with the returned merchandise (see the shipping instructions
below). This agreement simply ensures that you have not retained any copies of the
software, and have not permitted others to obtain copies from yours.

When DYNACOMP receives the returned merchandise accompanied by the signed
agreement, you will be issued a refund for the purchase price of the material minus a
25% restocking fee.

VARIATIONS ON THE REFUND THEME

1. If, instead of a refund, you wish to exchange for another product of equal or greater
price, you must still sign and return the Copyright Infringement Agreement with the
returned merchandise. However, in this case there is no restocking fee, and the
charge is only for the difference in purchase prices, plus $3.50 for shipping and
handling

2. If you received a quantity discount for purchasing three or more programs and your
return affects this discount, it will be factored into your refund.

3. If you purchased from a dealer and wish a refund, you must make arrangements with
that dealer according to his policy.

SHIPPING INSTRUCTIONS FOR RETURNS

1. Replacement of a defective cassette/diskette/disk: Return only the defective item,
not the documentation. Include your.sales receipt and a note stating the problem.
Carefully pack it (preferably using the protective packing in which it was originally
delivered). DO NOT FOLD, DO NOT BEND, FRAGILE, etc., markings do not appear to
ensure careful handling. Ask yourself: Would this package survive a 3,000 mile trip in
your car trunk in a bag full of groceries?

2. Return of merchandise for a refund: Pack as indicated above and include your sales
receipt, a note describing the problem, and a signed copy of the Copyright Infringe¬
ment Agreement.
